Answer:

A. The number of houses that an individual owns

Explanation:

The use of normal distribution in option A would produce an error. That is the number of houses individuals own.

We know that people can own 1 house or more than 1 house or no house at all. But a person can never be said to have less than 0 houses.

Option a is going to be skewed positively. Using Normal distribution would give us an error.
