I think its the 3rd. I'm like 80% sure

A decomposition reaction is where a complex molecule breaks down into simpler ones, so there must be more than one product.

The third statement is false. 

Decomposition reactions do require energy (heat), so the first is correct. 
The second statement is correct because decomposition reaction involves the breaking down of a molecule, so there will definitely be more than one product.
The third is false because in a decomposition reaction, it is the products which are less stable and more active.
The fourth statement is correct because decomposition reactions are the breaking down of  a molecule when energy is added. There is no interaction with any other molecules.
