**Core Concept**
Chromic catgut suture is a type of absorbable surgical suture made from the small intestine of animals, typically sheep. The addition of chromic salts to the suture material alters its properties, making it more resistant to enzymatic degradation.

**Why the Correct Answer is Right**
The chromic salts in chromic catgut suture slow down the action of enzymes, such as proteases and cathepsins, that break down the collagen in the suture material. This delay in enzymatic degradation allows the suture to remain intact for a longer period, resulting in delayed resorption. As a result, chromic catgut suture is commonly used for skin closure, muscle closure, and other tissue layers where a prolonged absorption period is desirable.

**Why Each Wrong Option is Incorrect**
**Option A:** No resorption is incorrect because chromic catgut suture is still an absorbable material that will eventually break down and be resorbed by the body.
**Option B:** No resorption is incorrect for the same reason as Option A.
**Option C:** Early resorption is incorrect because the addition of chromic salts actually delays the resorption process, not accelerates it.
**Option D:** Greater adherence is incorrect because the properties of chromic catgut suture do not affect its adherence to tissues; rather, it affects its rate of resorption.

**Clinical Pearl / High-Yield Fact**
When choosing between plain catgut and chromic catgut suture, consider the tissue type and the desired absorption period. Chromic catgut suture is suitable for skin and muscle closure, while plain catgut suture is often used for bowel anastomoses.

✓ Correct Answer: A. Delayed resorption.
