Women readily develop lower body fat around the hips and thighs and men readily develop central body fat around the abdomen. This primarily is due to gender differences in

a. set points.
b. the activity of lipoprotein lipase.
c. patterns of physical activity.
d. the activity of lipoprotein synthetase.
e. blood insulin levels.

b. the activity of lipoprotein lipase.

Explanation:

Lipoprotein lipase (LPL) is considered or known to be a rate-limiting enzyme that hydrolyzes circulating triglyceride-rich lipoprotein such as very low density lipoproteins and chylomicrons.

It is known that the Lipoprotein lipase is  activated by glucagon and adrenaline. And this why the activity of LPL increases in muscle tissue and decreases in adipose tissue, during fasting while , its activity decreases in muscles tissue and increases in adipose tissue.

It is known that, it  plays an important role in breaking down fat in the form of triglycerides, which are carried from various organs to the blood by molecules called lipoproteins.

In conclusion, women fat cells in the breasts, hips, and thighs produce abundant LPL, storing fat in those body sites  , while in men, fat cells in the abdomen produce abundant LPL.

equal distribution i think.

i'd have to say the answer is probable the second option "the geosphere interacting with the atmosphere"
