Answer»

Correct choice is (b) INCREASE in size is not appreciable

For explanation I would say: The other options being true, in animals there is a more strict regulation of GENE PRODUCT formation than in the CASE of PLANTS. In animals with an increase in cell size there would be a decrease in cell number keeping the ultimate animal sizes same. It is thus not profitable at all.
