Match List-I with List-II on the basis of two simple harmonic signals of the same frequency and various phase differences interacting with each other:

LIST-I (Lissajous Figure)		LIST-II (Phase Difference)
A.	Right handed elliptically polarized vibrations	I.	Phase difference = \( \frac{\pi}{4} \)
B.	Left handed elliptically polarized vibrations	II.	Phase difference = \( \frac{3\pi}{4} \)
C.	Circularly polarized vibrations	III.	No phase difference
D.	Linearly polarized vibrations	IV.	Phase difference = \( \frac{\pi}{2} \)
