The Correct Option is B
Solution and Explanation
When a person writes all numbers from 0 to 99, the digit '3' will appear in the tens place 10 times (30 to 39) and in the ones place another 10 times (3, 13, 23, ..., 93).
Therefore, the digit 3 will appear a total of 19 times. Hence, the correct answer is "19."
Therefore, the digit 3 will appear a total of 19 times. Hence, the correct answer is "19."
