Light rays from a ray-box travel through three lenses fitted at positions $1$, $2$ and $3$. What kind of lens is used at each position?
- Aposition 1: converging; position 2: converging; position 3: converging
- Bposition 1: converging; position 2: converging; position 3: diverging
- Cposition 1: diverging; position 2: converging; position 3: diverging
- Dposition 1: diverging; position 2: diverging; position 3: converging
