To evaluate candidates' understanding of nuclear composition and related changes, a specific question was designed for NEET (UG) 2024 using the NCERT Physics Textbook for Class 12 (Part II). The question included Statement II: "Atoms of most of the elements are stable and emit their characteristic spectrum," making option (Statement I correct, Statement II incorrect) the initially correct answer. Upon receiving 27,020 answer key challenges, including 13,373 For this question, experts reviewed the ambiguity due to differences in the old and new editions of the NCERT textbook. Based on expert opinion, the answer key was updated to reflect that Statement II should be: "Atoms of each element are stable and emit their characteristic spectrum," as per the old textbook. Consequently, two options were considered correct. This was also done as a policy mentioned in the Information Bulletin of the NEET (UG) – 2024 i.e. “If more than one option is found to be correct then Four marks (+4) will be awarded to only those who have marked any of the correct options”.
