If a one gram sample of water vapor condenses to a liquid and then freezes to a solid how much total energy will have been released?

Option A, Calcium hydroxide

Explanation:

Sports pitches are regularly marked with the chalk and limestone. However, in earlier sports events,  wood shavings and dust were also used.  

Since most of these sports are played on grass surfaces, marking through lime has proved much convenient than other materials.  

Chalk and limestone materials or hydrated lime (CaOH) is crushed into powder form and used for marking the pitches. Since it is white in color, it could easily reflect the light  and hence produces good  visibility.

Hence, option A is correct
