Final answer:
The value of x in the given data should be 4, as the mode is also 4. Hence the correct answer is option A
Step-by-step explanation:
The mode of a data set refers to the value(s) that occur(s) most frequently. In this case, the mode is 4. To determine the value of x in the given data, we need to find the number that occurs most frequently. Since the mode is already 4, the value of x should also be 4.
Therefore, the answer is A. 4.
