Answer: Option A

Solution(By Examveda Team)

An alleochemical beneficial to releaser only is called Allomone.
An allomone is a type of semiochemical produced and released by an individual of one species that affects the behaviour of a member of another species to the benefit of the originator but not the receiver.
Allomones are allelochemicals that evoke in the receiver of the signal a behavioral (releaser effect) or physiological response (primer effect) that is adaptively favourable to the sender but not the receiver.
