• B. hydrolysis
• C. perpetual motion
• D. chemical bonds that hold atoms together in chemicals

Answer 1

The correct option is D chemical bonds that hold atoms together in chemicals

It is a specific type of thermal energy.

It is released in a chemical reaction, often producing heat as a by-product (exothermic reaction).

Hence the correct option is D.
