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

Which of the following definitions best describes 'mesonephric juxtaglomerular apparatus development'?

A. The process whose specific outcome is the progression of the juxtaglomerular apparatus in the mesonephros over time, from its formation to the mature structure. The juxtaglomerular apparatus is an anatomical structure which consists of juxtaglomerular cells, extraglomerular mesangial cells and the macula densa. The juxtaglomerular apparatus lies adjacent to the glomerulus and regulates kidney function by maintaining the blood flow to the kidney and the filtration rate.
B. The series of events by which a mechanical stimulus is received and converted into a molecular signal.
C. The process whose specific outcome is the progression of the juxtaglomerular apparatus in the metanephros over time, from its formation to the mature structure. The juxtaglomerular apparatus is an anatomical structure which consists of juxtaglomerular cells, extraglomerular mesangial cells and the macula densa. The juxtaglomerular apparatus lies adjacent to the glomerulus and regulates kidney function by maintaining the blood flow to the kidney and the filtration rate.
D. A spatially aggregated collection of nerve cell bodies in the CNS, consisting of one or more subpopulations that share cell type, chemical phenotype, and connections, and including nearby cells that share the same cell type, chemical phenotype, and connections. (CUMBO).

The juxtaglomerular apparatus is an anatomical structure which consists of juxtaglomerular cells, extraglomerular mesangial cells and the macula densa.
