VSPER (Valence Shell Electron Pair Repulsion) Theory -

Valence shell electron-pair repulsion theory (VSEPR theory) enables us to predict the molecular structure, including approximate bond angles around a central atom of a molecule from the estimation of the number of bonds and lone pairs of electrons in its Lewis structure. 

-

As we have learnt,

The shape of a molecule depends upon the number of valence shell electron pairs (bonded or non- bonded) around the central atom. These pair of electrons in the valence shell repel one another since their electron clouds are negatively charged.
Hence , option number (3) is correct.
