Answer: b

Explanation: The remote's infrared pulses deliver energy to the TV receiver while no mass is transferred. (Photons carry energy and momentum but have no rest mass.) Options a and c are incorrect because EM waves are transverse and photon energy is directly proportional to frequency (E = hf), and d is incorrect because EM waves do not "accelerate" in air.
