Bond order, bond length, and bond energy are closely related. The shorter a bond, the its bond strength. A shorter bond will therefore have a higher bond energy than a longer bond. Bond order also plays a role. For a given pair of atoms, the higher the bond order, the shorter and the bond will be.

greater, stronger

Explanation: Bonds that form as a result of sharing their electrons are called covalent bonds. A lot of energy is contained in those bonds, especially if they are higher order. A single bons is bond order 1, A triple bond is bond order 3. An example of a triple bond is acetylene. It combusts with a very hot flame when it's triple bond is broken with oxygen.

elements make up everything, and they combine to make compounds.

the answer is c

it would be b. 6co2 + 6h2o --> c6h12o6 + 6o2
