Which of the following is a large bean-shaped lymphoid organ in the human body?

Spleen

The correct answer is Option (2)- Spleen

The large bean-shaped lymphoid organ in the human body is the Spleen.

Explanation:

The spleen is an important organ of the lymphatic system and is located in the upper-left side of the abdomen, beneath the ribcage. It acts as a blood filter, removing damaged blood cells and platelets, as well as serving a role in immune response by producing antibodies and storing immune cells. The spleen also plays a role in storing platelets and releasing them into the bloodstream when needed.

While lymph nodes, tonsils, and the thymus are also parts of the lymphatic system and contribute to immune function, the spleen is particularly recognized for its large size and its role in blood filtration.
