well its the Right Renal Artey Being Constricted therefore its concerntration of Renin in its Vein will be increased as compared to the Left Renal Vein which has no constriction of Artey but will express the Constriction due to Presence of INC Renin Plamsa values but itself wont secrete renin.

Now i was oscillating bw Choices 2 and 4 wondering which wud be the correct one but in the end went 4 cos the pathology is in the Right Kidney.
