Answer: C.
Reason: A (√49 = 7) is rational. B (1/3 = 0.333...) is a repeating decimal, hence rational. D (−1/8 = −0.125) is a terminating decimal, hence rational. C, written as 0.12345678... with no repeating pattern, is a nonterminating, nonrepeating decimal and therefore not rational (irrational).
