An object approaches a convergent lens from the left of the lens with a uniform speed \[5\text{ }m\text{ }{{s}^{-1}}\] and stops at the focus. The image

• A.  Moves away from the lens with a uniform speed \[5\text{ }m\text{ }{{s}^{-1}}\]
• B.  Moves away from the lens with a uniform acceleration
• C.  Moves away from the lens with a non-uniform acceleration
• D.  Moves towards the lens with a non-uniform acceleration.
