Explanation for the correct option:

Convert hexadecimal equivalent of decimal number $785$

Decimal number is based on $10$numbers that are $0,1,2,3,4,5,6,7,8,9$. But hexadecimal base on $0,1,2,3,4,5,6,7,8,9,A,B,C,D,E,F$. These $A,B,C,D,E,F$ use as a single digit in place of $10,11,12,13,14,15$.

To convert a decimal into hexadecimal number, we divide the decimal number by $16$ and note the remainder. Again divide the quotient by $16$and note the remainder. The process goes ahead until we get $0$ as a quotient. Then note the remainder in reverse order means from bottom to up.

$785÷16=49$, remainder is $1$

$49÷16=3$, remainder is $1$

$3÷16=0$, remainder is $3$

The hexadecimal equivalent of decimal number $785$ is $311$.
Hence option B is the correct option.
