Short answer

Option (c) 6 variables, 2 of which are categorical is correct.

Step-by-step solution

Step 1. Given information.

The given statement is:

The given table contains data for ten persons picked at random from the survey's more than 1 million household contacts.

Step 2. Choose the most appropriate response.

First, we have to identify the variables:

We can observe from the table that the variables include Weight, Age, Travel to Work, School, Gender, and Income last year.

In total, they are 6.

Now classify them as categorical or quantitative:

Weight, Age, Gender, and Income last year are quantitative variables.

Travel to Work, and School are categorical variables.

Therefore option (c) is correct.
