The correct answer is A. maintaining homeostasis.
Homeostasis is a term referring to an organisms continuous process of maintaining and auto-regulating the conditions of its internal environment. Variables such as pH, temperature, and fluid balance need to be at optimal conditions in order for the organism to function properly.
In this example, the phosphate buffer system permits the organisms to maintain a constant pH in their intracellular fluid. This is one of the organism's homeostatic mechanisms.

During week 2 of the menstrual cycle (day 8 to day 14 or
ovulation), estrogen levels rise until it reaches its peak. Typically, days
12-14 have the highest levels of estrogen, which causes an increase in Luteinizing Hormone, which is responsible for the release of the egg cell. If
hormone levels fail to reach its peak before day 14, ovulation is not possible
because the egg cannot be released. Pregnancy may be highly unlikely.
