Step-by-step explanation:
The correct answer is c) 2+.
On the edema (swelling) scale, a depression that takes more than 30 seconds to rebound is classified as 2+ edema. This means that the skin remains indented for a significant period before returning to its normal shape.
For example, if you press your finger firmly into the skin and it takes more than 30 seconds for the indentation to disappear, it would be classified as 2+ edema.
