- towards the left as its potential energy will increase.
- towards the right as its potential energy will decrease.
- towards the left as its potential energy will decrease.
- towards the right as its potential energy will increase.

The Correct Option is B
Solution and Explanation
As the electric field will loose its strength in the rightward direction. So, the force on $(+q)$ will be more then the force on $(-q)$
$\left|\vec{F}_{1}\right|>\left|\vec{F}_{2}\right|$
Hence the dipole will move towards right as in the direction of electric field potential reduces
$\left|\vec{F}_{1}\right|>\left|\vec{F}_{2}\right|$
Hence the dipole will move towards right as in the direction of electric field potential reduces
