A) make a testable hypotheses
The other ones make sense, just not for the question :)
You wouldn’t hide experimental data, as it could hurt your credibility (b)
You should always support your claims by evidence, this is why we use the scientific method :) (c)
Since it’s a question of science, the hypothesis shouldn’t be the one to answer an ethical question (d)
The answer is A I hope this helps! :))
