Answer #1

Solution:

Ans: E

All of the above are true,

Reason:

The speed of light in a vacuum is 186,000 miles per second

= 3*1010 cm/s  

and its the fastest signal in the universe.

I hope you understood the problem and got your answers, If yes rate me!! or else comment for a better solutions.
