Answer:
The correct option is d.
Explanation:
For a question to be answered by an experiment, some conditions need to be satisfied.
An experiment must follow qualitative analysis. In a sense, an experiment must be able to be quantified. Let's take an example:
Suppose a school wants to screen candidates for an entrance level. The candidates must be of a specified number. The exam is taken. The exam scores are tabulated and distributed according to the statistical distribution. In this way, the quantitative distribution in the candidates pass mark cab be quantified.
In the question, the correct option will be d. The program can be tested quantitatively (and generating data).
