Testes (C) is the right choice. This sits at the heart of Reproductive System: the wording points straight to what is happening in the tissue or organ system. A useful study habit is to ask what the structure or process is for: Testes is the option that correctly names the structure, process, or principle asked for in Reproductive System. That reasoning supports Testes. One solid sentence about why this works is enough for recall — you do not need a long essay for every MCQ. When you practise, cover the choices first, write Testes from memory, then reveal the letter — that habit builds real recall for Reproductive System.
