Answer:

Explanation:

- **Identifying the Correct Answer**
The correct answer to this question is option 'C'.

- **Reasoning**
In this question, the symbol '?' is used to represent a missing number or operation. To find the missing value, we need to look for a pattern or relationship between the given numbers.

- **Analyzing the Given Numbers**
Looking at the given numbers, we can observe that the first two numbers are related as follows:
4 x 2 = 8

Similarly, the last two numbers are related as:
6 x 2 = 12

Therefore, we can infer that the missing number should also be obtained by multiplying the first number by 2.

- **Calculating the Missing Number**
Calculating the missing number using this pattern:
7 x 2 = 14

Hence, the missing number should be 14.

- **Conclusion**
By applying the pattern of multiplying the first number by 2, we can determine that the missing number is 14. Hence, option 'C' is the correct answer.
