Solution

The correct option is B Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion.
Club fungi are the fungi which belong to the group basidiomycetes. Rusts and the smuts are the type of club fungi. These fungi attack the cereal crops like oats, wheat, etc. The rusts and smuts infect the cereal crops to produce spores because these fungi cannot produce the basiodiocarps.
The smuts enter the seeds and then infect the cereal crops. The smuts produce spores which are visible when they reach maturity. These spores are dispersed when they reach maturity to form new fungus.
Both the assertion and reason are correct but the reason is not the correct explanation for the assertion.
Thus, the correct answer is option B.
