In this task, you're given a question, a context passage, and four options which are terms from the passage. After reading a passage, you will get a brief understanding of the terms. Your job is to determine by searching and reading further information of which term you can answer the question. Indicate your choice as 'a', 'b', 'c', or 'd'. If you think more than one option is plausible, choose the more probable option to help you answer the question.

Passage:Born on the New Year's Day of 1966 at Khargapur in the Indian state of Madhya Pradesh, Sangita Mukhopadhyay completed her MSc with a gold medal and did her doctoral studies at the Regional Medical Research Center, Bhubaneswar which fetched her a Phd from Utkal University in 1998 for her thesis on immunoregulation in filariasis. Subsequently, she did the post-doctoral work at the National Institute of Immunology and, later, in U.S.A. at the University of Texas Health Science Center at Houston. On her return to India, she joined the Central Drug Research Institute in 1999 and after a short stint, moved to the Centre for DNA Fingerprinting and Diagnostics (CDFD). She later became the head of the Molecular Biology Group at the Laboratory of Molecular and Cellular Biology of the institute and holds the position of a Grade IV staff scientist. At her laboratory, she hosts many research scholars who are involved in the studies in the disciplines of cell signaling and signal transduction, immunity, macrophage biology and tuberculosis.

[EX Q]: Question: Was Willemstad successfully defended against the French in 1793? Passage:By the 1790s Braak was in the Caribbean, and was present at the defence against the French of Willemstad, part of the Dutch colony at Curaçao, in 1793. By late 1794 she was ordered to escort a convoy of East Indiamen to Batavia in the Netherlands East Indies. En route she called at the English port of Falmouth, unaware that the French had since invaded the Netherlands and proclaimed the Batavian Republic as a client state, compelling the Dutch to declare war on the British. On the arrival of the convoy at falmouth, the Royal Navy seized the 26 merchantmen and six warships of the convoy, including De Braak. A boarding party from the sloop-of-war took over De Braak. Forty-six Royal Navy vessels that were at Plymouth shared in the prize money.

[EX Q]: Question: What is the official IAU name for the main star that is ioninizing  the surrounding material? Passage:Sharpless 264, also known as the Lambda Orionis Ring, is a molecular cloud and H II region, which can be seen in the northern region of the Orion Molecular Cloud Complex (OMCC), in the constellation of Orion. The OMCC is one of the best-known star formation regions and the closest sector of the Milky Way to our Solar System where high-mass stars are born. The nebula is named after its main star, λ Orionis, a blue giant responsible for the ionization of the surrounding material. It is also sometimes called the Angelfish Nebula due to its resemblance as to its lighter areas (pink to peach colour) to an angelfish. In the infrared its ionized boundaries are that which appears, instead.
