Solution

The correct option is D Assertion is incorrect but Reason is correct
|z45i|=4 represents a circle with centre (4, 5) and radius 4.
arg(z34i)=π4 represents a ray emanating from point (3,4)
Ray will intersect the circle at only one point.
So statement (I) is false and statement (II) is true.
