Question Analysis
This question involves categorizing the variable representing the count of text messages sent in a day. The main focus is on applying the definitions of discrete and continuous variables to this specific scenario.

Key Concept Explanation
Discrete variables consist of distinct, separate values that are obtained by counting. You can't have a fraction of a text message in this context, so the possible values are whole numbers (0, 1, 2, 3, ...).
Continuous variables, however, can take any value within an interval and are measured, not counted.

Step-by-Step Solution
1. Remember the difference: discrete = counted, continuous = measured.
2. The question is about the number of text messages, which is counted. You can't send half a text message in a meani...
