Explanation

$\textbf{Hint: Time taken by sunlight to reach earth is 8 min and 20 seconds.}$

$\textbf{Correct option: Option (A).}$

$\textbf{Explanation:}$

$\textbf{Step 1:Time taken by sunlight to reach earth.}$

Time taken by sunlight to reach earth, $t=8\min ,20\sec$

$\Rightarrow t=8\times 60+20=480+20=500\operatorname{s}$

$\textbf{Step 2: Calculating the distance of sun from earth.}$

We know that the velocity of light, $c=3\times {{10}^{8}}m{{s}^{-1}}$

The distance of sun from earth will be,

$distance=velocity\times time$

$\Rightarrow d=c\times t=(3\times {{10}^{8}}m{{s}^{-1}})\times 500s=150\times {{10}^{9}}m=150\times {{10}^{6}}km$

$\textbf{Thus, distance of sun from earth is 150 million kilometers. Hence, option (A) is correct.}$
