The correct answer is $\boxed{\text{A}}$.
To convert a binary number to decimal, you can use the following formula:
$$decimal = \sum_{i=0}^{n-1} d_i \cdot 2^i$$
where $d_i$ is the $i$th digit of the binary number, starting from the right, and $n$ is the number of digits in the binary number.
In this case, the binary number is $10110112$, which has 8 digits. The digits are $1$, $0$, $1$, $1$, $0$, $1$, $1$, and $2$.
Plugging these values into the formula, we get:
$$decimal = 1 \cdot 2^7 + 0 \cdot 2^6 + 1 \cdot 2^5 + 1 \cdot 2^4 + 0 \cdot 2^3 + 1 \cdot 2^2 + 1 \cdot 2^1 + 2 \cdot 2^0 = 8110$$
Therefore, the decimal equivalent of $10110112$ is $\boxed{8110}$.
The other options are incorrect because they do not represent the decimal equivalent of $10110112$.
