Task: Class Definition Understanding (ontology: Sciences/Biology)

Which of the following definitions best describes 'ureteric bud formation'?

A. The process in which nicotinamide mononucleotide is transported across a membrane. Nicotinamide mononucleotide is a ribonucleotide in which the nitrogenous base, nicotinamide, is in beta-n-glycosidic linkage with the c-1 position of d-ribose. It is a constituent of NAD and NADP.
B. The developmental process pertaining to the initial formation of a mesonephric nephron tubule from unspecified parts. A mesonephric nephron tubule is an epithelial tube that is part of a nephron in the mesonephros.
C. The developmental process pertaining to the initial formation of the ureteric bud from the Wolffian duct. This process begins when the bud protrudes from the duct and ends when it is a recognizable bud.
D. Any process that stops, prevents or reduces the frequency, rate or extent of protein localization to adherens junction. An adherens junction is a cell-cell junction composed of the epithelial cadherin-catenin complex at which the cytoplasmic face of the plasma membrane is attached to actin filaments.

Answer: The developmental process pertaining to the initial formation of the ureteric bud from the Wolffian duct. This process begins when the bud protrudes from the duct and ends when it is a recognizable bud.
