Photoelectric Effects and deBroglie Equation: Practice Problem & Solution

An electron of mass m and a photon have same energy E. The ratio of de-Broglie wavelengths associated with them is (c being velocity of light) (2016-I)
$\frac{1}{c} \left(\frac{E}{2m}\right)^{\frac{1}{2}}$
$\left(\frac{E}{2m}\right)^{\frac{1}{2}}$
$c(2mE)^{\frac{1}{2}}$
$\frac{1}{c} \left(\frac{2m}{E}\right)^{\frac{1}{2}}$
