Explanation:

Question 28

A freckle is a small brown spot, a papule is a small solid bump, a bulla is a large blister with watery fluid, and a sac is a general pouch - like structure. So the correct answer is the one that matches a large blister with watery fluid.

A keloid is an excessively thick scar from fibrous tissue overgrowth, a bulla is a blister, a cyst is a closed sac with fluid/semisolid, and a stain is a discoloration not related to scar tissue. So the correct answer is the one related to thick scar from fibrous overgrowth.

A lesion is a general abnormal area, a macule is a flat discoloration spot, a pustule is a pus - filled bump, and a bulla is a blister. So the correct answer is the one for a flat discoloration spot.

c. bulla
