A simple telescope, consisting of an objective of focal length 60 cm and a single eye lens of focal length 5 cm is focussed on a distant object in such a way that parallel rays emerge from the eye lens. If the object subtends an angle of `2^@` at the objective, the angular width of the image is :

A

`10^@`

B

`24^@`

C

`50^@`

D

`(1//6)^@`.
