Practice question

Kidney tubules (B) is the right choice. This sits at the heart of Tissue-I: 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: Kidney tubules is the option that correctly names the structure, process, or principle asked for in Tissue-I. That reasoning supports Kidney tubules. 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 Kidney tubules from memory, then reveal the letter — that habit builds real recall for Tissue-I.
