Answer:

option (C) 20cm

Explanation:

To form real and inverted image of same size

that of the object, the object should be placed at C1 or 2F1(centre of curvature) on the left side of the convex lens. Now

if focel length=10cm

then Radius of curvature (R)=2f=20cm

which is equal to object distance(u)=20cm
