Answer:

C.2/7+√121

Step-by-step explanation:

C is the only answer with the square root being a whole number while the rest of the answers' square roots are not whole number answers and the numbers after the decimal go on forever thus making it an irrational number. Also, for B, pi is not a rational number.
