Correct Answer: OPTION c: 0

Explanation:

The given heights (in cm) are: 152, 148, 150, 153, 147.

Steps:

1. Arrange the heights in ascending order: 147, 148, 150, 152, 153.
2. Calculate the \(\text{median}\): The middle value in the ordered list is 150 cm.
3. Calculate the \(\text{mean}\): \( \frac{147 + 148 + 150 + 152 + 153}{5} = \frac{750}{5} = 150 \) cm.
4. Determine the difference between the mean and median: 150 - 150 = 0

Since both the mean and median are 150 cm, the difference is 0.

Final Answer: \(\boxed{0}\)
