List I contains four combinations of two lenses (1 and 2) whose focal lengths (in cm) are indicated in the figures. In all cases, the object is placed 20 cm from the first lens on the left, and the distance between the two lenses is 5 cm. List II contains the positions of the final images. List-I List-II (I) (P) Final image is formed at 7.5 cm on the right side of lens 2. (II) (Q) Final image is formed at 60.0 cm on the right side of lens 2. (III) (R) Final image is formed at 30.0 cm on the left side of lens 2. (IV) (S) Final image is formed at 6.0 cm on the right side of lens 2. (T) Final image is formed at 30.0 cm on the right side of lens 2. Which one of the following options is correct?

1. I → P, II → R, III → Q, IV → T,
2. I → Q, II → P, III → T, IV → S
3. I → P, II → T, III → R, IV → Q
