Solution

The correct option is B Bread mould
In the life cycle of Rhizopus(Bread mould), during sexual reproduction, gametangia are similar in structure called as isogametangia. They are fused together, and form into a thick walled zygote. It undergoes meiosis, leads to the formation of spores.
So, the correct option is 'Bread mould'.
