• B. Carbohydrates, lipids, proteins, and nucleic acids
• C. Proteins, nucleic acids, enzymes, and hormones
• D. Carbohydrates, lipids, vitamins, and minerals

Answer: (B)

Verified step by step guidance

1. Identify the four major groups of biological molecules that are essential for life processes.
2. Understand that carbohydrates, lipids, proteins, and nucleic acids are the primary categories of macromolecules in biology.
3. Recognize that amino acids are the building blocks of proteins, and nucleotides are the building blocks of nucleic acids, not separate major groups.
4. Note that enzymes and hormones are functional proteins, and vitamins and minerals are not considered macromolecules.
5. Conclude that the correct grouping of the four major biological molecules is carbohydrates, lipids, proteins, and nucleic acids.
