At postition D the 135 degrees must point towards the south-east not south-west. The P is moving from C to D.

We are not moving 35 degree we are moving 135 degree.

We are facing east when at point D. 135° means it will be as in the fig shown, which direction should he go ?
a) If to get home he should go south-east.
b) If to continue the past he should go south-west.
a) If to get home he should go south-east.
b) If to continue the past he should go south-west.

From A to B p is in west direction and B to C is in north direction C to D is in east direction.
We know that from north to east, south, west north angle is 360 degree therefore.
N to E 90 degree, E to S 90 degree, S to W 90 degree, W to N 90 degree.
Now p is in east direction given that p turns 135 degree.
135 degree = 90+45 degree.
From 90 degree p is in south again 45 degree so p is in south west direction.

From 90 degree p is in south again 45 degree so p is in south west direction.

This is incorrect.
"After this, he is to turn right at 135 degrees".
The diagram in the solution depicts that 'P' is already facing right (south) before deciding an angle of continuation. Which conflicts with the description of 'P's movement. Should 'P' have turned right at 135 degree angle from his prior Eastward bearing, the angle would have 'P' traveling South-East.
Simply match the base of a protractor atop 'P's Eastward bearing and you'll notice in the diagram given in the solution the creator of this question assumes P is already facing right, before then taking another slight turn of 135 degrees; two turns would be needed for the diagram depictions to be correct. The language of the description only indicates one fluid movement of 135 degrees.

Yes, It should be South-East.
Nisha said:

The correct answer should be South-East, if p wanted to get home.

According to the diagram, we have to turn right at 135 from point D, so he will move towards south-west.
We have to see direction from point D.
We have to see direction from point D.
