A beam of radiation is passed between a pair of charged plates as indicated in the fig above. Beam P is undetected While Q is deflected to the left. P and Q respectively should be

I.γ-rays β-rays
II. x-rays β-rays
III. γ-rays x-rays
IV. x-rays x-rays

OPTION C IS LEGIT
Beam P is uncharged (so passes straight IT could be γ-rays or x-rays).
Beam Q is charged (so deflects must be β-rays).
Only options where P is γ or x and Q is β are correct I and II which is Option C

The answer should be C. Xrays are also uncharged hence will not be deflected by the charged plates
