Answer: Option B

Explanation: A gene is the specific portion or sequence on the DNA (Deoxyribonucleic acid) that is able code for a functional protein. Thus, the entire DNA sequence in each cell consists of several genes and some non-coding portions that all makes up the complete hereditary information usually called genome.

Observe this linear chain

Cell -> Chromosomes -> DNA -> Gene.

The above illustrates that a gene is the basic carrier of hereditary information.

This will definitely help.
