Solution

The answer is the second one (2): spleen.

Explanation for each option:

Tonsils: The tonsils are part of the lymphatic system and help protect against pathogens entering through the mouth and throat, but they do not destroy worn-out red blood cells.
Spleen: The spleen's major job includes filtering the blood, destroying worn-out red blood cells, and returning some of the breakdown products to the liver. It also plays a role in immune response.
Thymus gland: The thymus gland is involved in the maturation of T-lymphocytes (T-cells), which are crucial for the adaptive immune system, but it does not destroy red blood cells.
Tonsils: This is a repeat of option 1 and is incorrect for the same reasons.
Peyer's patches: Peyer's patches are small masses of lymphatic tissue found in the small intestine, which monitor intestinal bacteria populations and prevent the growth of pathogenic bacteria in the intestines. They do not destroy red blood cells.

Summary: The spleen is the lymphatic organ responsible for destroying worn-out red blood cells and returning some of the products to the liver.
