JEE Main 2019 Physics question

A convex lens is put 10 cm from a light source and it makes a sharp image on a screen, kept 10 cm from the lens. Now a glass block (refractive index 1.5) of 1.5 cm thickness is placed in contact with the light source. To get the sharp image again, the screen is shifted by a distance d. Then d is:

• (A)0.55 cm towards the lens
• (B)0
• (C)0.55 cm away from the lensCorrect
• (D)1.1 cm away from the lens
