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

Which of the following definitions best describes 'obsolete modulation by host of symbiont signal transduction mediated by G-protein gamma subunit'?

A. OBSOLETE. Any process in which the host organism modulates the frequency, rate or extent of the symbiont signal transduction mediated by G-protein gamma subunit. The host is defined as the larger of the organisms involved in a symbiotic interaction.
B. OBSOLETE. Catalysis of the reaction: cathasterone + O2 + a reduced electron acceptor = teasterone + H2O + an oxidized electron acceptor.
C. OBSOLETE. Specification of the borders of posterior gap gene expression mediated largely by the effects of other gap genes; in insects this is exemplified by hunchback and tailless repression of knirps.
D. OBSOLETE. Exports diffusible peptide signals that are responsible for binding to other cells and triggering a series of responses to facilitate mating.

Answer: OBSOLETE. Any process in which the host organism modulates the frequency, rate or extent of the symbiont signal transduction mediated by G-protein gamma subunit. The host is defined as the larger of the organisms involved in a symbiotic interaction.
