Which of the following is true regarding the properties of light? a. light needs a medium to propagate through a vacuum. b. light can only travel in a straight line. c. light is not able to display interference or diffraction. d. light has a dual nature and acts like both a wave and a particle

Option (d) is correct.

Light has a dual nature and acts like both a wave and a particle. This theory was given by Einstein. There are some properties which can be explained only if we consider light as a wave like interference, diffraction , polarization etc . Some other properties like black body radiation, photoelectric effect can be only explained if we consider light as a particle. So, we say that light has dual nature. Light is made of packets of energy called as photons.
