Answer 1

As the position of an object (u) reflected from a concave mirror is varied, the position of the image (v) also varies. For the values of u from 0 to +`oo,` the graph between v versus u will be

 

Explanation:

At u = 0, v = 0 (i.e., object and image both lies at pole), At u = f, v = `oo`. These two conditions are only satisfied by option (A).
