b. 2.5 mg of atorvastatin lowered cholesterol levels the most.
c. the biggest change in cholesterol levels occurred between weeks 2 to 6 of any dose.
d. the biggest change in cholesterol levels occurred during the first 2 weeks of any dose.

Explanation:

• Option A: The 80 mg line has the largest negative change (lowers cholesterol the most), so A is wrong.
• Option B: The 2.5 mg line has the smallest negative change (lowers cholesterol the least), so B is wrong.
• Option C: All lines show a much smaller change between weeks 2-6 compared to baseline-week 2, so C is wrong.
• Option D: Every dose line has the steepest drop (largest change) between baseline and week 2, with smaller changes afterward.

Answer:

D. The biggest change in cholesterol levels occurred during the first 2 weeks of any dose.
