For women, there are things called "Sperms". There is an <em>egg </em>in the women. Think of colors. Say an orange sperm is a boy and a yellow sperm is a girl. If the yellow sperm reaches the egg first, the baby will be a girl. If the orange sperm reaches the egg first, the baby will be a boy. Think of it as a Sperm-race.
If two yellows, two oranges, or one of each comes to the sperm at the same time, you'll have twins.
Same with triples, quadruplets, etc, even though this is very rare.

It's a riddle
The heart is the primary organ, which pumps blood through the body. The heart automatically adjusts the blood flow to match the activity levels by the intake of more oxygen.
The heart functions appropriately in the presence of oxygen. During a time of activity or an exercise, the body requires an extra amount of energy to meet the needs of the activity. The heart adjusts itself by taking up more oxygen so that the blood flow is increased and the oxygen demand is met.
The heart pumps necessary blood volume to different parts of the body such that, the body does not suffer from any physiological problems.
Thus, the heart sets the blood flow by taking up more oxygen. The correct answer is Option B.
