Somatic vs germ-line: Which description accurately contrasts somatic interventions?

Explanation:
The main idea here is how genetic changes behave across generations. Somatic interventions modify cells in the body and do not get passed to children. Germ-line interventions target reproductive cells—eggs, sperm, or early embryos—and those changes can be inherited by future offspring. Describing germ-line modifications as inheritable directly contrasts with the non-inheritable nature of somatic changes, which is why this description best captures the difference. The other statements either describe somatic changes without emphasizing the inheritance aspect, or assign the wrong inheritance pattern to germ-line or somatic modifications.
