B
occurs when part of a chromosome breaks off and reattaches backward on the same chromosome
C
occurs when part of a chromosome breaks off and does not reattach
D
occurs when part of a chromosome breaks off and attaches to another chromosome

Explanation

Insertion occurs when a chromosome segment breaks off and is inserted into another chromosome, typically within its length. Choice A describes this process. Reattaching backward is an inversion, failing to reattach is a deletion, and attaching to another chromosome is a translocation.
