The difference between smallest two-digit odd number and the largest three digit even number is an
A. odd number
B. even number
C. can’t say anything
D. none of these

Hint: In this problem, we have to find the difference between the smallest two-digit odd number and the largest three-digit even number. We know that the smallest two-digit odd number is 11 and the largest three-digit even number is 998. We can now find the difference between them and we can find the type of the resulting answer, whether even or odd to find the final answer.

Complete step by step solution:
Here we have to find the difference between the smallest two-digit odd number and the largest three-digit even number.
We know that the smallest two-digit odd number is 11.
We also know that the largest three-digit even number is 998.
We can now find the difference between the smallest two-digit odd number and the largest three-digit even number by subtracting them, we get
\[\Rightarrow 998-11=987\]
Here we can see that the resulting answer is an odd number.
Therefore, the difference between the smallest two-digit odd number and the largest three-digit even number is an Option A. odd number.

Note: We should always remember the smallest and the largest digit number to solve these types of problems, we should remember that the largest three-digit even number is 998 and the smallest two-digit odd number is 11. We can subtract them and see the last digit of the resulting value to find whether it is odd or an even.
