Covalent bonds involve the sharing of electron pairs between atoms. Electron pairs shared between atoms of equal or very similar electronegativity constitute a nonpolar covalent bond (e.g., H–H or C–H), while electrons shared between atoms of unequal electronegativity constitute a polar covalent bond (e.g., H–O). Created by Sal Khan.

According to Classical or earlier concept oxidation is a process which involves the addition of oxygen or any electronegative element or the removal of hydrogen or any electropositive element. According to electronic concept oxidation is defined as the process in which an atom or ion loses one or more electrons.Steps in the β-Oxidation of Fatty Acids. Further oxidation of the fatty acyl-CoA occurs in the mitochondrial matrix via a sequence of four reactions known collectively as β-oxidation because the β-carbon undergoes successive oxidations in the progressive removal of two carbon atoms from the carboxyl end of the fatty acyl-CoA (Figure \(\PageIndex{1}\)).Electrolysis. Electroplating. Electrolysis refers to the breaking apart of a molecule by the means of the electrochemical reaction. Electroplating refers to the passage of current through the solution with metal such that it gets deposited on one of the electrodes. Electrolysis is good for carrying out the non-spontaneous chemical reactions.An oxidising agent will gain electrons because it undergoes reduction itself and a reducing agent will lose electrons because it undergoes oxidation itself. So, the correct answer is “Option C”.
