Which best describes what Shah is doing?

The answer is A. Replication

Explanation:

In an experiment, replication is the process of repeating an experiment that was formerly conducted by another experimenter in order to ensure accuracy. Note that, an experiment is 'replicated' under the same conditions as it was conducted previously.

This is the case in this question involving Shah who conducted an experiment herself because she didn't trust the results of the experiment she read about. She conducted an experiment that has already been conducted by another experiment, hence, it is a REPLICATION.
