Answer
This is the correct answer. When oil reacts with oxygen, a process called oxidation occurs, leading to rancidity. Rancid oils have undesirable flavors and odors.
Step 3

Answer
This option is also incorrect. The process of reacting with oxygen does not convert oils into unsaturated fats; in fact, unsaturation usually refers to the presence of double bonds that can be affected by oxidation.
