a. women are shorter than men, and shorter people are more stable.
b. men have more muscle mass in their lower bodies that makes them stiff and less stable.
c. women have lower centers of gravity, and lower centers of gravity provide more stability.
d. the increased muscle mass in their upper bodies makes their centers of gravity difficult to find.

False A.) Women are shorter than men, and shorter people are more stable... there are taller women, not every woman is short, not every man is tall
False B.) Men have more muscle mass in their lower bodies that makes them stiff and less stable... NOT true AT ALL... not every man has more muscle mass in lower body than upper...
True C.) Women have lower centers of gravity, and lower centers of gravity provide more stability
False D.) The increased muscle mass in their upper bodies makes their centers of gravity difficult to find... This can be applied to men NOT women. 

You did not show us the image of the burger, but i shall try to answer as best i can.  when purchasing food, always consider the ingredients as well as the person who prepared it. consider if they were hygienic people or not, in case the burger was infected with bacteria. no mortal should place an infected burger into their mouth.
