Answer : The correct option is, (b) 
Explanation :
Complete ionic equation : In complete ionic equation, all the substance that are strong electrolyte and present in an aqueous are represented in the form of ions.
Net ionic equation : In the net ionic equations, we are not include the spectator ions in the equations.
Spectator ions : The ions present on reactant and product side which do not participate in a reactions. The same ions present on both the sides.
The balanced molecular equation will be,

The complete ionic equation in separated aqueous solution will be,

In this equation the species
are the spectator ions.
Hence, the complete ionic equation contains specie is

Swimming pool has more thermal energy than bucket of water at the same temperature.
<h3>What is heat capacity?</h3>
Heat capacity or thermal energy is the amount of heat that is use by an object to produce a unit change in temperature or the heat absorbed by an to produce a change in temperature.
The heat capacity of an object total depends on the objects mass and chemical composition. Because of swimming pool have larger mass, it had larger heat capacity than bucket full of water even at the same temperature.
Therefore, Swimming pool has more thermal energy than bucket of water at the same temperature.
