Explanation / Answer

The histogram is right skewed. Thus it represents positively skewed distribution and not bell shaped distribution.

Thus we cannot use normal distribution as a model.

The answer is C. The histogram is not bell-shaped, so a normal distribution could not be used as a model for the variable.
