A-4°C
B0°C
C4°C ✓ Correct
D-2.5°C
Correct answer: (C) 4°C — Freshwater is densest at 4°C, so that is the answer.
Explanation
★Freshwater is densest at 4°C, so that is the answer.
★As water cools, it grows denser down to a certain point.
★That point is 4 degrees Celsius, where water is densest.
★Below 4°C the water becomes less dense again as it nears freezing.
★So freshwater achieves its greatest density at 4°C.
★So the answer is 4°C.
