JEE Main 2019 Chemistry question on Atomic Structure

The de-Broglie wavelength (λ\lambda) associated with a photoelectron varies with the frequency (vv) of the incident radiation as, [v0v_0 is threshold frequency]
  1. A.
    λ∝1(v−v0)12\lambda \propto \dfrac{1}{(v - v_0)^{\frac{1}{2}}}
  2. B.
    λ∝1(v−v0)32\lambda \propto \dfrac{1}{(v - v_0)^{\frac{3}{2}}}
  3. C.
    λ∝1(v−v0)\lambda \propto \dfrac{1}{(v - v_0)}
  4. D.
    λ∝1(v−v0)12\lambda \propto \dfrac{1}{(v - v_0)^{\frac{1}{2}}}
