detailed solution

Correct option is D

Slime moulds are saprophytic protists. Under suitable conditions, they form an aggregation called plasmodium which may grow and spread over several feet. Plasmodium is wall less. During unfavourable conditions, the plasmodium differentiates and forms fruiting bodies bearing spores at their tips. The spores possess true walls. They are extremely resistant and survive for many years, even under adverse conditions. The spores are dispersed by air currents.
