So, Firstly
Light is the natural agent that stimulates sight and makes things visible.
and speed of light means that the distance covered by the light with respect to time.
So, it means those distance which is covered by the light with respect to time is called the speed of light.
The speed of light is measures in km, meters and in other units also.
And we can calculate the speed of light per hour or per minute or in other time measurements.
So, The speed of light is 300,000 kilometers per hour. hence option c is correct.

use this formula
Step-by-step explanation:
Use the distance formula.
d = √[(x2 - x1)2 + (y2 - y1)2]
You have all of the coordinates. Plug in the numbers and evaluate.
