Hexane is a compound. All chemical compounds can be broken down by chemical change (chemical reactions of many types) - not only hexane. All the other choices are elements which cannot be broken down by chemical changes.
The bonds in a molecule can break and atoms can bond with other atoms.
All of the elements of the Periodic Table cannot be broken down into simpler substances.
Elements can not be made into simpler substances even by chemical reactions. Compounds can be broken down to simpler substances and eventually to elements. One useful observation is that an element will burn to give only one product, whereas a compound will give more than one.
I believe the question is Can bones be broken. The answer is yes. One major cause is the side-effects of the medicine used for arteriosclerosis.
By definition, a compound can, somehow, be broken down into its elements. Whether this process is easy depends on the strength of the chemical bonds in the compound and the definition of "easy"!

During chemical reactions bonds are broken.
yes, they can only be broken down by chemical means
it is broken down to fuel chemical reactions & is created by chemical reactions.

Chemical bonds are made and broken by chemical reactions. After chemical bonds have been broken, then energy is released, and if a chemical bond is made, then energy is absorbed.
This is a chemical reaction.
