Practice question

Umbilical cord (B) is the right choice. This sits at the heart of Tissue-2: 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: location matters here: Umbilical cord is the structure or site that matches the description. That reasoning supports Umbilical cord. 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 Umbilical cord from memory, then reveal the letter — that habit builds real recall for Tissue-2.
