• B. a rational number
• C. an irrational number
• D. a natural number

Answer 1

The correct option is B

a rational number

Given is $2.35$,

$2.35$is a rational number because it is a terminating decimal.

Note: Terminating decimal numbers has a finite number of digits after the decimal point.

A number with a terminating decimal is always a rational number. If the denominator of a rational number can be expressed in form $2^p{5}^q$or $2^p$ or $5^q$, where $p,q\in N$, then the decimal expansion of the rational number terminates.

Hence, the correct option is (b).
