D Correct answer
Explanation

From 100 to 120 inclusive, counting the digit 1 appearing in the ones place: numbers ending in 1 (101, 111) = 2 ones; the number 10 in 110 contributes another 1; and the tens digit 1 appears in 100-109 (10 times) and 110-119 (10 times), plus one more in 100's hundreds place and 110's hundreds place. Total = 34, making option D correct.
