The correct option is A If both the assertion and the reason are true and the reason is a correct explanation of the assertion
A life cycle characterized by a haploid thallus, and zygotic meiosis is called plantings life cycle. It is also called as haplobiontic because only a single type of free living individual is involved in the life cycle. Spirogyra shows plantings life cycle and therefore, it also shows zygotic nucleus.
