C Correct answer
Explanation

Pi (π) is an irrational number, meaning its decimal representation never terminates and never settles into a permanently repeating pattern. While the digits continue infinitely, they are not "recurring" in the strict mathematical sense because recurring implies a repeating pattern like 0.333... Pi's decimal digits continue unpredictably without repetition. Option C is correct as pi is infinite, though "non-recurring" would be more precise than "infinite".
