Answer:

1. B. Oxidation

2.This unappetizing phenomenon is actually due to a chain of biochemical reactions known as “enzymatic browning.” When an apple is injured (or cut into pieces), the plant tissue is exposed to oxygen. ... This results in new chemicals (o-quinones), which then react with amino acids to produce brown-colored melanins.
