Solution

The correct option is D If both the assertion and reason are false
In eusporangiate type of development, large sporangia develop from a group of initials.
In leptosporangiate type of development, small sporangia develop from a single initial, the former builds the entire sporangium, its contents and stalk and the latter takes no part in the process.
Hence both the assertion and reason are wrong and the correct option is D.
