Carbon is the essential component of all organic compounds.
Assuming a pupil is a human being, the average adult human body contains about 16% carbon by weight. So in a 60kg pupil, there would be approximately 9.6kg of carbon.
The human body is made up of only mostly carbon, oxygen, hydrogen, nitrogen, calcium, and phosphorus. The top four elements are oxygen, carbon, hydrogen and nitrogen, so that would be a. on your list.

Given that giraffes and human beings are both mammals the compositions of the bodies of the two species might not be all that different. The human body is 18% carbon by mass, and 12% of the atoms in a human body are carbon atoms. There is some variation between people owing to levels of body conditioning, hydration, health and so on. This would apply to giraffes as well.
Carbon has a property to form a chain. This unique property of carbon gives it upper hand. So you have organic versus non-organic chemistry. There can be variety of chemicals with carbon only. So life without carbon is impossible.
Human body is organic in nature. Organic compounds are formed mostly of carbon, nitrogen, oxygen and hydrogen. So you have these elements in your body in very high proportion.
Makes it feel so much better
Your hair is made out of dead cells. It is the way of the human body.

The bond formed with carbon is essentially the covalent bond. So all the organic molecules in your body has got covalent bond.
so the human body can produce the 'air' and leave it so the body does fill up.
Well the human body is made of 70 to 75% water, So it's 7 out of 10
