An electric dipole is situated in an electric field of uniform intensity `E` whose dipole moment is `p` and moment of inertia is `I`. If the dipole is displaced slightly from the equilibrium position, then the angular frequency of its oscilliations is
A. `((pE)/(I))^(1//2)`
B. `((pE)/(I))^(3//2)`
C. `((I)/(pE))^(1//2)`
D. `((p)/(IE))^(1//2`
