Which of the following can occur by the process of meiosis but not mitosis?

a) haploid cells fuse to form diploid cells.
b) haploid cells multiply into more haploid cells.
c) diploid cells form haploid cells.
d) a diploid cell combines with a haploid cell

C). Diploid cells form haploid cells.

Explanation: meiosis is a cell division process taking place in both prokaryotes and eukaryotes which leads to the development of more cells as it is seen with diploid(double or combined) cells dividing to form haploid(single) cells. This type of cell division can be seen taking place leading to the production of sex cells like in humans. Sex cells like spermatozoa and ovules.

The sphores of green algae are also produced through meiosis.
