Answer

Correct option: A.
Polarity of bonds in molecules
a
By using Pauling's electronegativity values for elements, the polarity of molecules is predicted. If electronegativity difference is high, molecule is highly polar and it the electronegativities of two elements are similar or almost similar, the bond formed between them is non-polar.
