Solution
The correct option is A East
As per the question, proton is falling under gravity and the direction of magnetic field →B is towards North.
From the given information we can take the direction of →v and →B as ^v=−^j and ^B=−^k respectively.
Now, the direction of magnetic force on a charged particle is,
^Fm=^v×^B=−^j×−^k=^i
As the charge on the proton is positive, so the direction of →F will be towards East.

Hence, it will deflect towards East.
