Solution

The correct option is C f1+f2
For L1, rays are coming from infinity and hence, image is formed at focus.
v1=f1

For L2, rays after refraction, become parallel to principal axis. Hence, object for second lens is at its focus.
u2=f2

Distance between the lenses from the diagram given in the problem is:
L=v1+u2=f1+f2
