A region in the form of an equilateral triangle (in $$x - y$$ plane) of height $$L$$ has a uniform magnetic field $$\vec{B}$$ pointing in the $$+z$$-direction. A conducting loop $$PQR$$, in the form of an equilateral triangle of the same height $$L$$, is placed in the $$x - y$$ plane with its vertex $$P$$ at $$x = 0$$ in the orientation shown in the figure. At $$t = 0$$, the loop starts entering the region of the magnetic field with a uniform velocity $$\vec{v}$$ along the $$+x$$-direction. The plane of the loop and its orientation remain unchanged throughout its motion.

Which of the following graph best depicts the variation of the induced emf ($$E$$) in the loop as a function of the distance ($$x$$) starting from $$x = 0$$?
