• A. 5 cm, 30 cm, 40 cm
• B. 5 cm, 35 cm, 45 cm
• C. 10 cm, 450 cm, 65 cm
• D. 5 cm, 45 cm, 85 cm

Answer 1

The correct option is B 5 cm, 35 cm, 45 cm

$\begin{array}{c}\text{Where.}\\ I_{1x}=\text{Image}1\text{with respect to}x\end{array}$

$I_{2x}=$ Image 2 with respect to $x$

$I_{3x}=$ Image 3 with respect to $x$

$I_{1y}=$ Image. 1 with respect to $y$

So, $5,35,45cm$

are the required

distances option' $B$ ' is correct
