Explanation
Answer: A - The phase of tissue healing in which the body produces collagen is fibroblastic/ proliferation phase. The phase starts on day 3 and lasts until day 21, beginning with the building of collagen in the wound which will eventually form a scar. The wound can withstand normal stresses within 2-3 weeks and strength continues to build for several months.
