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

Which of the following definitions best describes 'regulation of trans-synaptic signaling'?

A. Any process that modulates the frequency, rate or extent of retrograde trans-synaptic signaling by neuropeptide.
B. Any process that modulates the frequency, rate or extent of action potential creation, propagation or termination in an SA node cardiac myocyte. This typically occurs via modulation of the activity or expression of voltage-gated ion channels.
C. Any process that modulates the frequency, rate or extent of cell communication that contributes to the shaping of the growth plate cartilage.
D. Any process that modulates the frequency, rate or extent of trans-synaptic signaling.

Answer: Any process that modulates the frequency, rate or extent of trans-synaptic signaling.
