1. Electron pairs are always repelling each other and tries to     remain far apart

2. Different electron pairs have different orders of repulsion:              L.P-L.P > L.P-B.P > B.P-B.P

3. If lone pairs are not present then geometry is equal to shape else geometry is not equal to the shape.

This all is explained by V.S.E.P.R. theory.
Hence, option number (2) is correct.
