you are correct because that not an experiment its a question

Answer: Option (c) is the correct answer.

Explanation:

An experiment conducted by following a detailed and organized series of steps in such a manner that its result will reject or validate the hypothesis.

For example, using an acid-base indicator will help to measure the pH of a solution.

A scientific reaction is performed in controlled conditions with proper precautions unless it could be dangerous to perform the experiment.

Therefore, we can conclude that she asks her lab partner which base he thinks is hardest to study is not a scientific experiment.
