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

Which of the following definitions best describes 'response to iron ion starvation'?

A. Any process that results in a change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a starvation stimulus, deprivation of nitrate.
B. Any process that results in a change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a starvation stimulus, deprivation of molybdenum.
C. The process whose specific outcome is the progression of the myxococcal fruiting body over time, from its formation to the mature structure. The process begins when myxococci respond to a lack of nutrients in the environment and ends when the myxococcal fruiting body is a mature structure.
D. Any process that results in a change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a starvation stimulus, deprivation of iron ion.

Answer: Any process that results in a change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a starvation stimulus, deprivation of iron ion.
