Verified step by step guidance

Understand that antibody diversity is crucial for the immune system to recognize a wide array of antigens.

Recognize that gene rearrangements refer to the process of V(D)J recombination, which is a primary mechanism for generating antibody diversity by rearranging variable (V), diversity (D), and joining (J) gene segments.

Note that splicing is a process that can contribute to diversity by allowing different exons to be joined together, resulting in different protein isoforms, including antibodies.

Consider that mutations, particularly somatic hypermutations, occur in the variable regions of antibody genes, further increasing diversity by introducing point mutations.

Identify that apoptosis is a process of programmed cell death and does not contribute to the generation of antibody diversity, making it the correct answer to the question.
