Solve the following grid puzzle: If X is the missing number, which option is correct? X & 6 96 & 4 \ Options: A. 12 B. 10 C. 15 D. 24 E. 30

The grid is given as:

$$\begin{bmatrix} ? & 6 \\ 96 & 4 \end{bmatrix}$$

Let the missing number be $X$.

Consider the numbers in the bottom row: 96 and 4.
Consider the numbers in the right column: 6 and 4.

A common pattern in these types of problems is a simple arithmetic relationship between the numbers. Let's test if the number in the bottom-left cell divided by the number in the bottom-right cell gives the missing number in the top-left cell.

If the pattern is $X = \frac{\text{Bottom-Left}}{\text{Bottom-Right}}$, then:

$$X = \frac{96}{4} \\ X = 24$$

The calculated missing number is 24.
The given options are:
A. 12
B. 10
C. 15
D. 24
E. 30

The calculated value matches option D.

The final answer is $\boxed
