Answer:

A. The length (in minutes) of the longest telephone call made in a day - This data is numerical and continuous as the value is calculated by a measuring process.

B. Whether someone in the household owns a smart phone -  It is a categorical variable as this question can only be yes or no.

C. The number of cell phones in the household - It is a numerical variable which is discrete as counting is used to answer this.
