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.

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.

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

Earth is rotating from the west to east, there the person running in the east direction the rain appears in the east direction.

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

According to vectors formula. It appears that the relative direction should be coming from the northwest.

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

You are running eastwards, so rain drops will appear coming from the east [in front of you].

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