A.) Collect water samples from the Mediterranean Sea for analysis in order to understand where they live.

Step-by-step explanation:

While developing a study a certain topic, a scientist has to take into consideration the ethical and practical implications of the techniques that are going to be used to execute the study. Techniques that are less invasive and put the least pressure on the subject of study, must be prioritized. Options B.) and C.) require the subject to be moved to an environment that can be detrimental to their health which is not ideal. Option D.) is not practical and could cause other ethical problems, as it would mean placing the fish in a foreign environment. The correct answer is A.) as it is simple and ethical.
