The variable whose changes we wish to study is called

Explanation:
The idea here is identifying the outcome you’re examining in a study. The variable whose changes you wish to study is the response (or dependent) variable—the measurement that reflects the effect you’re trying to understand. For example, if you’re looking at how study time influences exam results, the exam score is the response variable because you’re interested in how it changes in relation to study time. The explanatory (independent) variable is the factor you think explains or drives those changes, such as hours studied. The other options aren’t about the variable of interest: questionnaires and respondents are parts of data collection, not the outcome you’re analyzing.
