Vedclass · Answer

(A) The classification of eggs is based on the amount and distribution of yolk:$1$. Centrolecithal eggs have yolk concentrated in the center,which is characteristic of insects.$2$. Macrolecithal (or Megalecithal) eggs contain a large amount of yolk,found in birds and reptiles.$3$. Microlecithal eggs contain a small amount of yolk,found in eutherian mammals.$4$. Alecithal eggs contain almost no yolk,found in eutherian mammals (though often classified as microlecithal due to trace amounts).Therefore,the pair $A$ (Centrolecithal egg - Insect) is correct.
