Practice question

Pick C: Trapping and movement of mucus. Thinking about Tissue-I in a practical way — what the structure does, or what the process achieves — leads you here. Clinically and academically, the same logic shows up again and again: the functional job described in the stem is exactly what Trapping and movement of mucus does in Tissue-I. Hence Trapping and movement of mucus is correct. Treat this as a building block for the rest of Tissue-I; neighbouring topics often reuse the same principle. Keep a one-line summary card for this idea and revisit it before the paper; short, repeated review beats long cramming sessions.
