At normal atmospheric pressure, water freezes at:
a. -20 °c
b. 0 °c
c. 100 °c
d. 120 °c

Water will freeze at 0°C so the answer is b

Hi there! Your answer would be B. 0°C. Just like water at a lake, that water is a liquid and when it freezess it eventually becomes a solid. Now, you could ice skate on the lake, but make sure that the water is absolutely frozen.
