Answer: Brand A at 2.40 dollars per litre
Compute unit price for Brand A: $3.60 \div 1.5 = 2.40$ dollars per litre. Compute unit price for Brand B: $5.00 \div 2 = 2.50$ dollars per litre. Compare and conclude: Brand A (2.40 dollars/litre) is cheaper per litre than Brand B (2.50 dollars/litre). Why distractors fail: Option B: Correctly states Brand B's unit price but presents it as the lower one. Option C: The two unit prices differ. Option D: $2.00$ per litre would require $2.00 \times 2 = 4.00$ dollars, not 5.00.
