The correct answer is A. 10110112.

To convert a decimal number to binary, you can use the following steps:

1. Divide the decimal number by 2.
2. Write down the remainder.
3. Divide the quotient by 2.
4. Write down the remainder.
5. Continue dividing and writing down the remainders until the quotient is 0.
6. Starting from the bottom, read the remainders from right to left.

For example, to convert 89 to binary, you would do the following:

1. 89 / 2 = 44 with a remainder of 1
2. 44 / 2 = 22 with a remainder of 0
3. 22 / 2 = 11 with a remainder of 0
4. 11 / 2 = 5 with a remainder of 1
5. 5 / 2 = 2 with a remainder of 1
6. 2 / 2 = 1 with a remainder of 0

The remainders are 1, 0, 1, 0, 1, 0. Reading these from right to left, we get the binary number 10110112.
