However, had it been a real sound, the sound's pitch would have been increased by the Doppler Effect, since the Falcon was moving _____ the source of the sound.

perpendicular to

away from

towards

at the same speed as

Answer 1

I believe the answer is C.

Answer 2

Towards

Step-by-step explanation:

According to Doppler Effect, there is change in the apparent frequency of the sound heard by the listener, when the source and the listener have relative motion.

The apparent frequency (pitch) increases when the source and the listener approach while it decreases when the source and listener recede away from each other.

Sound's pitch is related to frequency. With increase in frequency, pitch increases. If the Falcon was moving towards the source, the sound's pitch would have increased.
