Answer 1

The correct option is A All of the above

Sponge-Bisexual/monoecious/hermaphrodite
During sexual reproduction, an individual sponge is capable of producing both sperms and eggs. Thus, they can be considered as bisexual, hermaphrodite or monoecious as a single organism possesses both male and female reproductive structures.

Leech-Bisexual/monoecious/hermaphrodite
Leeches possess both male and female sex organs in a single organism and are capable of producing both male and female gametes. Thus they are considered to be bisexual, hermaphrodite nd monoecious.

Cockroach-Unisexual/Dioecious
In cockroaches, male and female reproductive organisms are present on separate individuals and hence they are considered to be unisexual or dioecious.

Frog-Unisexual
Frogs too have male and female sex organs in separate organisms and are hence unisexual or dioecious.

Date palm-Dioecious
Date palm has male and female flowers on separate plants and is hence considered to be dioecious.
