Correct answer: C — Proliferative phase
The proliferative phase of wound healing (approximately days 3-21) is characterised by fibroblast migration and proliferation, collagen deposition, angiogenesis (new blood vessel formation), and granulation tissue formation. The inflammatory phase (days 1-3) involves neutrophil and macrophage infiltration. The remodelling phase (weeks to months) involves collagen cross-linking and scar maturation.
