unimodal.

Explanation:

Part a

To determine modality, we check the number of peaks (modes) in the distribution curve. A unimodal distribution has one peak, bimodal has two, and multimodal has more than two. From the context (and typical skewed distributions), the curve likely has one peak. So the distribution is unimodal.

For symmetry, a symmetric distribution has the left and right sides mirror - images. A nonsymmetric (skewed) distribution has one side stretched out more. Since the curve is likely skewed (as part c is about skewness), the distribution is nonsymmetric (or skewed).

For a unimodal and nonsymmetric distribution, we classify skewness. A right - skewed (positively skewed) distribution has a long tail on the right, and a left - skewed (negatively skewed) has a long tail on the left. From the curve (assuming the typical right - skewed shape for such problems), the correct option is related to right skewed. But looking at the options, we need to match. Wait, the options seem to have a typo, but if we assume the correct option for a unimodal and right - skewed distribution (if the curve has a long right tail), and from the given options, if we consider the standard, for a unimodal and right - skewed distribution, the correct choice (assuming the options are about skewness and the curve is right - skewed) would be:
If we assume the curve is right - skewed (long tail on the right), and the options are about the classification. But from the given options (A - D), maybe there was a typo. But based on the problem, if the distribution is unimodal and nonsymmetric (right skewed), and if we assume the correct option is (for example, if A is "The distribution is right skewed", B is "The distribution is left skewed" etc., but from the given options as per the image, maybe the intended correct option is related to right skewed. But based on the initial problem, for part c, if the curve is right - skewed (long tail on the right), the answer is right skewed. But from the given options in the image (A - D with some text missing), assuming the correct option is the one that says the distribution is right skewed (if A is that). But maybe there was a formatting error. However, based on the standard skewness:

If the distribution is unimodal and has a long tail on the right, it is right skewed. So the correct option (assuming the options are A: right skewed, B: left skewed, C: something else, D: not unimodal) would be A (if A is right skewed). But since the text in the options is partially missing, but based on the problem's context, the answer for part c (if the curve is right - skewed) is right skewed.

But to match the options, let's assume the correct option is:

Answer:

unimodal
