Correct option (a) 24
Explanation
Synergids are two, short-lived, haploid cells lying close to the egg in mature embryo sac of flowering plant ovule. While the endosperm is a triploid tissue formed after triple fusion. Thus, if the synergids have 8 chromosomes, the aleurone layer (part of endosperm) will have just triple of that of chromosomes in the synergids, i.e. 24 chromosomes.
