The correct answer is option (A) Both produce sex cells.
Organisms reproduce sexually by the production of the sex cells. Ovaries and the testis are the important part of the female and male reproductive system respectively, producing the sex cells called the gametes. They are produced by the process of cell division called the meiosis.The female gamete is called an egg and the male gamete is called a sperm. Both are haploid in nature and during fertilization, they fuse to form a zygote. Human sex cells contain one complete set of 23 chromosomes.
Testes and ovaries are male and female reproductive organs, respectively. These organs are similiar as testes produce male gametes or sperms by the process of spermatogenesis and ovaries produce female gametes or ova by the process of oogenesis.
These gametes fuse together to form zygote that develops into a multicellular organism. Thus, the correct answer is 'option A). both produce sex cells.'
