A.
X-rays would be best because they are low-energy waves that can penetrate gases.
B.
X-rays would be best because they are high-energy waves that can penetrate solids.

B
X-rays are high-energy, short-wavelength electromagnetic waves that can penetrate solids like luggage and reveal internal contents (with differing absorption showing different materials). Radar (radio/microwave) waves are much lower energy and longer wavelength and do not give the needed resolution through dense materials.
