Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Why is Carbon used for all of life’s major biomolecules, such as Carbohydrates, Proteins, Nucleic Acids, and Lipids?
A
Carbon can form 4 bonds
B
Carbon is relatively stable
C
Carbon is relatively common on Earth
D
All of the Above
Explanation: 

Detailed explanation-1: -Life on earth would not be possible without carbon. This is in part due to carbon’s ability to readily form bonds with other atoms, giving flexibility to the form and function that biomolecules can take, such as DNA and RNA, which are essential for the defining characteristics of life: growth and replication.

Detailed explanation-2: -The reason is carbon’s ability to form stable bonds with many elements, including itself. This property allows carbon to form a huge variety of very large and complex molecules.

Detailed explanation-3: -Biomolecules are an organic molecule that includes carbohydrates, protein, lipids, and nucleic acids. They are important for the survival of living cells. Some of valuable biomolecules have huge demand, which cannot be fulfilled from their renewable resources.

Detailed explanation-4: -Because a C atom can form covalent bonds to as many as four other atoms, it’s well suited to form the basic skeleton, or “backbone, ” of a macromolecule.
