A double convex lens made of a material of refractive index `mu_1`, is placed inside two liquids of refractive indices `mu_2` and `mu_3` as shown `(mu_1gtmu_2gtmu_3)` A wide parallel beam of light is incident on the lens from the left. The lens will give rise to
A. a single convergent beam
B. two different convergent beams
C. two different divergent beams
D. a convergent and a divergent beam
