A negatively charged rod was brought near a jet of water running out from a burette. The jet of was deflected as shown

Regarding thus observation the correct statement is 

The deflection of jet of water towards negatively charged rod is due to attraction of water molecules by negative charged rod.

If the negatively charged rod is replaced by a positively charged rod the deflection of jet of water takes place in opposite direction

Instead of water if hexane and negatively charged rod are brought near, then also the liquid jet deflects away from the negatively charged rod

The interactions between negatively charged rod and the liquids water & Hexane are same.
