Concept:Hexadecimal gives humans a short, readable way to express long binary values.Explanation:Computers store and process data in binary, but binary strings become very long and hard to read.Hexadecimal is a base-$16$ system that uses the symbols $0$ through $9$ and $A$ through $F$.One hexadecimal digit represents exactly $4$ binary bits.So $1111_2$ becomes $F_{16}$, and $1010_2$ becomes $A_{16}$.This means a large value like $10110110_2$ is simply $B6_{16}$ in hexadecimal.As a result, programmers can read, write, and check values much faster with fewer visual errors.Hexadecimal is not more precise than binary; it stores exactly the same value.It also uses fewer digits than binary, not more.Therefore, the main advantage is convenience for human use.Answer:B. Easier to read and write
