A Correct answer
Explanation

The speed of light in vacuum is approximately 3 × 10^8 meters per second, a fundamental constant in physics. This value is denoted by 'c' and is the maximum speed at which all massless particles and waves can travel. The other options (10^9, 10^10, 10^11) are orders of magnitude too large. This constant is crucial in relativity and many areas of modern physics.
