Answer:
The statement is considered to be true
Explanation:
The statement is true because when elements chemically combine, there are interactions between their valence electrons, causing the two elements to be bonded together to form what is known as a compound. 
Compounds can only be formed from interactions between two or more elements. examples include:
Hydrogen + Oxygen = H2O (water)
Sodium + Chlorine = NaCl
Note that if atoms of the same element combine, what is formed is a molecule, not a compound. Some atoms usually do this to attain stability. examples include = O2 H2 and  N2. They are oxygen molecule, hydrogen molecule, and nitrogen molecule respectively.
Compounds are only formed when different elements combine to attain electronic stability.

B: The total thermal energy is greater in a large body of water than one much smaller
Explanation:
A large lake filled filled with cool water will have more thermal energy than smaller pond filled with warmer water because the total thermal energy is greater in a large body of water than one that is much smaller. 
Thermal energy is a form of kinetic energy usually due to transfer of heat energy. 
Amount of heat energy is dependent on the differences in temperature, mass and specific heat capacity of a body. 
Both lake water will have the same specific heat capacity. Since larger body of water has more mass, it will possess more thermal energy.
