How Do Germ-Line Mutations Differ from Somatic Mutations

How do germ-line mutations differ from somatic mutations?

A) Germ-line mutations involve small changes to DNA such as base-pair substitutions, while somatic mutations usually involve large deletions.
B) Germ-line mutations occur during DNA replication, while somatic mutations do not.
C) Germ-line mutations can be passed on to offspring, while somatic mutations cannot.
D) Germ-line mutations are reversible, while somatic mutations are not.
E) Germ-line mutations result in cancers, while somatic mutations do not.
