Polar molecule among given options is - (a) SF₄
Polarity of a molecule is the present of dipole moment characterized by partial positive and partial negative charge.
There are two types of molecules namely, symmetrical and unsymmetrical.
Symmetrical molecules have dipole moment where net charge is cancelled out due to structure of compound.
Unsymmetrical molecules dipole moment is not neutralized and they depict polarity.
Among the options given in question, SF₄ has unsymmetrical structure thus is polar in nature while others are symmetrical molecules.
