Answer:
Harmful mutations may cause genetic disorders or cancer. A genetic disorder is a disease caused by a mutation in one or a few genes. A human example is cystic fibrosis. A mutation in a single gene causes the body to produce thick, sticky mucus that clogs the lungs and blocks ducts in digestive organs.
Mutations arise spontaneously at low frequency owing to the chemical instability of purine and pyrimidine bases and to errors during DNA replication. Natural exposure of an organism to certain environmental factors, such as ultraviolet light and chemical carcinogens (e.g., aflatoxin B1), also can cause mutations.
only a small percentage of mutations cause genetic disorders—most have no impact on health or development. For example, some mutations alter a gene's DNA sequence but do not change the function of the protein made by the gene.

The answer would be D) All of the above because when it comes to peer pressure, it can make u sad and discouraged to do things u usually do, could lead to bad conduct such as: smoking, stealing or even being drunk, and this can lead to questionable friendships because when a friend makes u do something u don't want to do, u may think to yourself, is this person really my friend and does he/she consider me equal to them and not just a pawn.
Hope this helps.
