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

Which of the following definitions best describes 'regulation of metanephros development'?

A. Any process that modulates the rate, frequency or extent of metanephros development. Metanephros development is the process whose specific outcome is the progression of the metanephros over time, from its formation to the mature structure. The metanephros is an endocrine and metabolic organ that filters the blood and excretes the end products of body metabolism in the form of urine.
B. Any process that increases the rate, frequency or extent of kidney development. Kidney development is the process whose specific outcome is the progression of the kidney over time, from its formation to the mature structure. The kidney is an organ that filters the blood and excretes the end products of body metabolism in the form of urine.
C. Any process that decreases the rate, frequency or extent of metanephros development. Metanephros development is the process whose specific outcome is the progression of the metanephros over time, from its formation to the mature structure. The metanephros is an organ that filters the blood and excretes the end products of body metabolism in the form of urine.
D. Any process that decreases the rate, frequency or extent of kidney development. Kidney development is the process whose specific outcome is the progression of the kidney over time, from its formation to the mature structure. The kidney is an organ that filters the blood and excretes the end products of body metabolism in the form of urine.
