#(C) : theta = pi/4#

Explanation:

From rectangular to polar form ,#x=rcos theta # and

#y=r sin theta # where #r# is the distance from the origin to the

point, and #theta# is the angle measured from the positive 'x' axis

to the point:

Given #y=x :. cancelrsin theta= cancelr cos theta# or

#sin theta= cos theta or sin theta/cos theta=1 # or

#tan theta= 1 ; tan (pi/4)=1 :. theta = pi/4#

#(C) : theta = pi/4# [Ans]
