The distribution is not symmetrical and has a longer tail to the left, indicating that it is skewed to the left. Therefore, the correct option is D. Option A is incorrect since the skewness is towards the left, not the right. Option B is inappropriate since the binomial distributions give the probability of a certain number of successes in a fixed number of trials. Option C is inappropriate as the shape of the distribution is not bell-shaped, which is one of the characteristics of a normal distribution. Option E is also incorrect because there is only one mode, which is 25.
