Answer:
D. (Rational)
Explanation:
Natural : Counting numbers (1,2,3...)
Whole : Natural numbers including 0 (NO DECIMALS/FRACTIONS)
Integer : Whole numbers and their opposites (positive, negative.)
Rational : Any number that can be written as a fraction/decimal, a number that can terminate or repeat.
In this case, 0.2681 is rational because it is a terminating decimal.
