Water can keep engines operating at low temperatures. Which property of water most likely gives it this ability? A. it boils at around 100°C
B. it has a high heat capacity
C. it is a good lubricant
D. it can change from water to ice​

B: it has a high heat capacity

Explanation:

When any material has a high specific heat capacity/ heat capacity, it doesn't heat or cool very fast. So water can absorb more heat from the engine and can keep the engine cool or at low temperature for a longer period of time.
