Why Do the Meteors That Are Seen in the Sky

Why do the meteors that are seen in the sky in a particular meteor shower appear to come from one specific direction in the sky?

A) The meteors only appear to come from a specific direction because of Earth's orbital motion.
B) The meteors appear this way because the direction is that of the orbit of the comet that disintegrated to produce the shower.
C) This direction is always along the ecliptic plane because meteor showers occur when Earth catches up with a collection of particles moving in its orbit.
D) This direction is the one along which objects pass on being attracted to the Sun from outer space by the Sun's gravity.
