The correct answer is (A) - (v), (B) - (ii), (C) - (iv), (D) - (iii), (E) - (i).

Explanation:

Nerve cells:

• Nerve cells are long and branched because nerve cells require more surface area to pass signals from cell to cell.
• Their branch structure allows them to receive and transfer messages, allowing them to control and coordinate the functions of various parts of the body.

Red blood cells:

• Red blood cells are also called Erythrocytes. 
• ed blood cells are biconcave and disc-shaped.
• Size varies from 6 – 8 µm in diameter.

White blood cells:

• The white blood cells are also called Leukocytes. 
• White blood cells have no distinct shape.
• Size varies from 12 – 17 µm in diameter.

Muscle cell:

• Muscles are mostly made up of muscle cells, which are also known as muscle fibers.
• Each muscle cell is a long, thin cell.

Skin cell:

• Most of the skin cells are flat, scale-like squamous cells.
• These cells can also be found in the throat, the respiratory and digestive systems, and hollow organs like the kidneys.
