The correct option is B

In genetics, deletion (also called gene deletion, deficiency, or deletion mutation) is a mutation (a genetic aberration) in which a part of a chromosome or a sequence of DNA is lost during DNA replication. This results in huge difference in functionality of the respective protein.
