• B. RBCs
• C. Sperm
• D. Ovum

Answer 1

The correct option is D

Ovum

The correct option is D.

Explanation of the correct option:

1. The reproductive cell in a woman's body is termed an ovum, commonly known as an egg cell.
2. Ova has a diameter of roughly 0.1 mm and are 20 times larger than sperm cells.
3. The biggest cell in the body is the human egg (ovum).

Explanation of the incorrect option:

Option A:

1. The immune system of the body includes white blood cells.
2. They support the body's defenses against illness and infection.
3. The form of WBCs is asymmetrical.
4. The size ranges between 6 and 8 mm in diameter. The diameter ranges from 12 to 17 mm.

Option B:

1. The most prevalent form of blood cell and the main source of oxygen for the bodily tissues of vertebrates, red blood cells are also known as erythrocytes.
2. They circulate through the blood through the circulatory system.
3. The biconcave form of typical human RBCs has a diameter of 7-8 µm and a thickness of 2.5 µm.

Option C:

1. Male reproductive cells, often known as sperm or spermatozoa, are generated by most mammals.
2. Sperm is the first evolutionary examination of sperm phenotypes, derived sperm features, and potential selection pressures driving sperm-egg coevolution.
3. The sperm is the smallest cell in the human body.

Final answer: The largest cell in the human body is the ovum.
