Answer:

The best is letter "A"

Explanation:

The first option is the best because a hypothesis is a clear idea made by a researcher shown as an affirmative sentence that can be proven. The expression "will perform more poorly" is a verifiable idea. The second option is a question. The third and fourth options use modal verbs that leave an outcome vague.
