Living organisms contain many complicated molecules. Which of these is a

reason that carbon is important in these molecules?

D. carbon forms both single and and double bonds

Explanation:

A. a carbon atom can form a bond with only one other carbon atom.

B. carbon bonds with the lightest and smallest element.

C. a carbon atom can form only one bond at a time with another atom

D. carbon forms both single and and double bonds

The correct answer would be that carbon forms both single and double bonds.

Carbon is an important element in the various molecules of life because it is capable of forming both single and double bonds with other elements.

Due to the configuration of carbon, the element is capable of forming stable single and double bond with a wide variety of other elements, including itself. This thus enables carbon to form large and complex biomolecules which are important to life.
