• D. 1 - C, 2 - A, 3 - A, 4 - B

Answer 1

The correct option is B

1 - D, 2 - C, 3 - A, 4 - B

⇒since image height > object height and image is inverted.

⇒So, object must be kept between 2$F_1$ and $F_1$.

⇒since image height = object height,

⇒so object must be kept at 2$F_1$.

⇒since image height < object height' so

⇒object must be kept beyond 2$F_1$

d.

⇒ since image and object is at same side. So, only possibilities is object kept between focus and optical centre.
