* Somatic cells are the cells that make up the body of an organism. They are diploid, meaning they have two sets of chromosomes.

* Mitosis is a process of cell division that produces two identical daughter cells, each with the same number of chromosomes as the parent cell. This is how somatic cells are produced.

* Meiosis is a specialized cell division process that produces four haploid daughter cells (gametes), each with half the number of chromosomes as the parent cell. These gametes are involved in sexual reproduction.

Let's look at the other options:

* b. clones: Clones are genetically identical copies of an organism, often produced through asexual reproduction. While mitosis is involved in their creation, it's not the primary process defining them.

* c. zygotes: A zygote is a fertilized egg cell, formed by the fusion of a sperm and an egg. It's the first cell of a new organism and is diploid.

* d. spores: Spores are single-celled reproductive units that can develop into new organisms. They are produced by meiosis in some organisms.

* e. diploid cells: Diploid cells are cells with two sets of chromosomes. Somatic cells are diploid, but meiosis doesn't directly produce them.

Therefore, the correct answer is that somatic cells are produced by mitosis, while meiosis produces gametes.
