The question asks for the speed of light in a vacuum. The speed of light in a vacuum, denoted by c, is a fundamental physical constant. Its approximate value is 299,792,458 \, m/s, which is commonly rounded to 3 × 10^8 \, m/s. Let's examine the given options: a)* 3 × 10^8 \, m/s: This is the correct and widely accepted value for the speed of light in a vacuum. b)* 3 × 10^6 \, m/s: This value is incorrect; it is two orders of magnitude smaller. c)* 3 × 10^4 \, m/s: This value is incorrect; it is four orders of magnitude smaller. d)* 3 × 10^2 \, m/s: This value is incorrect; it is six orders of magnitude smaller. The correct speed of light in a vacuum is 3 × 10^8 \, m/s. The final answer is A
