◇1) air is the correct answer.

The refractive index of air is approximately 1 .

Less the refractive index of a medium, more the speed of light.

Materials in which particles are loosely packed are called Optically rarer medium.

Materials in which particles are tightly packed are called optically denser medium.

Light travels faster in rarer media as compared to denser media.
