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

Which of the following definitions best describes 'obsolete interaction with host via substance released by sporangium lysis'?

A. OBSOLETE. An interaction with the host organism mediated by a substance released via rupture of symbiont sporangia, structures producing and containing spores. The host is defined as the larger of the organisms involved in a symbiotic interaction.
B. OBSOLETE. (Was not defined before being made obsolete).
C. OBSOLETE. Any process that activates or increases the frequency, rate or extent of L-dopa decarboxylase activity.
D. OBSOLETE. The acetylation of the N-terminal threonine of proteins to form the derivative N-acetyl-L-threonine; catalyzed by peptide alpha-N-acetyltransferase.

Answer: OBSOLETE. An interaction with the host organism mediated by a substance released via rupture of symbiont sporangia, structures producing and containing spores. The host is defined as the larger of the organisms involved in a symbiotic interaction.
