Solution

The correct option is C Ascus
Yeasts can also reproduce sexually by means of sexual spores called ascospores which result from the fusion of the nuclei from two cells followed by meiosis. These ascospores stay within a unicellular structure known as an ascus. Each ascus bear 4 ascospores.
So the correct answer is option C.
