Since ABCD is a parallelogram, its opposite angles are equal (property of parallelogram)
Hence, angle(B) = angle(D)=(x+52) and angle (A) = angle(C)=3x
now we know that sum of all interior angles of a parallelogram is= 360
so, angle(A)+angle(B)+angle(C)+angle(D)=360
3x+(x+52)+3x+(x+52)=360
8x+104=360
8x=256
x=32
Hence, angle(A)=3x=3*32=96
so,option B is correct.
