Answer:

The correct answer would be B) carbon.

All organic compounds such as carbohydrates, fats, and proteins contain carbon as a common element.

Carbon is an element which has 6 as its atomic number and 4 as its valency that is, it can form four bonds at a time.

It can form long chains of itself which are sealed off with the help of hydrogen and thus form a hydrocarbon which is an important compound on earth.
