Work function WA for a photoelectric material A is 2 eV & WB for another photoelectric material B is 4 eV. If the photons of energy EA strike with surface of A the ejected photoelectrons have minimum de-Broglie wavelength A and photons of energy EB strike the surface of B, the ejected photoelectrons have minimum de-Broglie wavelength B. Where EB= (EA+0.5) eV and B =2A, VA and VB are respective stopping potentials then which of the following is not correct
**Options:**
- **A.** EA = 4 eV
- **B.** EA = 4.5 eV
- **C.** VA = 2 Volts
- **D.** VB =0 .5 Volts
