Which of the following is a reproductive

Solution

Gametes are specialized reproductive cells involved in sexual reproduction. In humans, sperm (male gamete) and ovum/egg (female gamete) are examples. These cells are haploid, containing only half the normal chromosome count (23 chromosomes in humans instead of the normal 46), which enables the restoration of the full chromosome number when fertilization occurs. Gametes are produced through meiosis, a specialized cell division process that ensures genetic variation. The other options—lymphocytes, RBCs (red blood cells), and WBCs (white blood cells)—serve immune or oxygen-transport functions but are not involved in reproduction.
