The correct answer is: Both involve the removal of organs.

Explanation:

Tonsillectomy and splenectomy are surgeries that involve the removal of organs. Tonsillectomy is used to remove the tonsils, while in a splenectomy the organ removed is the spleen. In fact, the suffix "-tomy" refers to the action to cut something.
