a. by performing a survey

b. in a laboratory

c. out in the field

d. by using scientific laws

Explanation:

• Option a: Surveys are for collecting data from people, not for chemical experiments. Eliminate a.
• Option b: Laboratories provide controlled environments with necessary equipment to conduct chemical reactions and isolate products. This is suitable for a chemist's controlled experiment.
• Option c: Fieldwork is for studying natural phenomena in their natural setting, not for controlled chemical reactions. Eliminate c.
• Option d: Scientific laws describe phenomena but don't perform experiments. Eliminate d.

Answer:

b. in a laboratory
