Assertion: If a dielectric is placed in external field then field inside dielectric will be less than applied field. Reason: Electric field will induce dipole moment opposite to field direction.

Dipole moment will be in the same direction as the external field. The collective effect of dipole moments produces a field that opposes the external field and hence, the net electric field inside the dielectric is less than the external electric field.
