To determine

To choose the correct option from the multiple choice question for the question.

Answer to Problem 83E

The option (c) is the correct option.

Explanation of Solution

It is given the four diets are:

Normal diet with unrestricted salt

Vegetarian diet with unrestricted salt

Normal diet with restricted salt

Vegetarian diet with restricted salt

We then note that we either have a normal or a vegetarian diet which is the first factor. We also then note that we have the option between restricted and unrestricted salt which is the second factor.

Thus there are two factors: normal/vegetarian diet and unrestricted/restricted salt. Thus option (c) is the correct option.
