Answer #1

Oxidation means loss of electrons during a reaction by a molecule, atom or ion, at that time oxidation state of a molecule, atom or ion is increased and that can be caused by removal of hydrogen atom.

When in a molecule hydrogen get removed then the central atom aquire more positive character which means oxidation state of the molecule increase

now in option (a) the reaction is C5H10O → C5H12O , here in product the number of hydrogen atom increased so it is not the example of Oxidation reaction

Similarly in option (b) C8H16 → C8H18 number of hydrogen atom increased, so it is also not the example of Oxidation reaction

but in option (c) C7H14O2 → C7H12O2 here number of hydrogen atom decreased in product(H14 → H12) which signify the oxidation state of C increased here that mean it the example of oxidation reaction

so option C is the right option
