Answer

$C_2H_4O_2$ (acetic acid)

Work Step by Step

Option (c) is given as acetic acid. The molecule of acetic acid has two oxygen atoms bonded to the carbon or hydrogen atom. The two polar covalent bonds are formed when the two highly electronegative oxygen atoms bind to the carbon or hydrogen atoms, resulting in the unequal sharing of the electron pairs. Hence, option (c) is correct.
