Can anybdy give an appropriate reason for this answer

With vertical, the rel-velocity will be inclined and appear to be coming from east. So the right answer is east.

It can also be in the northeast direction.

As the man is having an acceleration eastwards, a pseudo force will act on the rain drops towards the opposite direction so it will appear to go towards west and coming from east.

Resultant velocity can be determine by completing parallelogram law of vectors hence resultant velocity is northeastwards so man feels rain comes from the north east.

As the man is moving towards east, by relative motion the rain appear to come from the east.

As from above I can't understand clearly. So please tell me in fully explanation.

To me the rain should be coming from the North east. Let V1 be the velocity of rain, and V2 be the velocity of the man. The velocity V12 of rain relative to man V12 = V1-V2.
If you try to draw a vector diagram for the above, the direction of V12 will be along/with an arrow pointing down. Hence rain will appear coming from north east.

I thought it was west since you're running eastward you will feel it going westward because it dropping from your front to yourself.

It should be north - west direction from vector method.
