The correct response is:

The outermost shell can form up to four covalent bonds and this allows it to form biomolecules.

This property of carbon is crucial for life because it enables the formation of a diverse array of complex molecules, such as proteins, nucleic acids, carbohydrates, and lipids, which are essential for the structure and function of living organisms.
