Answer : a
Hints & Solutions
(a) Aleurone layer is the layer formed by the endospermic tissue in the members of family graminae e.g. wheat, rice, maize etc. Obviously it will be a triploid tissue. So if synergids have 8 no. of chromosomes which are haploid than aleurone- layer must have 24 chromosomes.
