b. the subject of the experiment has been studied by other scientists.

c. the experiment has a very simple procedure.

d. collecting samples to analyze is very expensive.

Explanation:

• Option A: A large number of constants in an experiment is good as it helps control variables, not a limitation.
• Option B: Previous studies by other scientists can provide a basis for the experiment, not a limitation.
• Option C: A simple procedure is efficient and not a limitation.
• Option D: If collecting samples is very expensive, it can restrict the amount of data or the scope of the experiment, which is a limitation.

Answer:

D. Collecting samples to analyze is very expensive.
