Answer:
d. uniform
Explanation:
If the data is uniformly distributed i.e. it follows Uniform Probability Distributions then it can be visualized by a histogram. Then the shape of the histogram will be bell-shaped which means as the value of x is increases the value of y also increases for small values of y and it will decrease for a large value of y.
But, other types of probability distributions can't be visualized by a histogram.
Hence option (d) is correct.
