Practice question

5α-reductase (B) 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: 5α-reductase is the option that correctly names the structure, process, or principle asked for in Reproductive System. That reasoning supports 5α-reductase. 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 5α-reductase from memory, then reveal the letter — that habit builds real recall for Reproductive System.
