Solution

The correct option is A 1.65 km
The distance between two points is calculated using the given formula.
Distance = Speed $\times$ Time.
Given that the speed of sound in air is 330 meters per second and the time taken is 5 seconds, distance covered can be calculated as follows.
$D = 330 m / s \times 5 s = 1650 m$
Hence, Paheli is at a distance of 1.65 kilometers from the lightning spot.
