Answer:
C) time-lapse photography
Step-by-step explanation:
The frequency at which film frames are taken is far lower than the frequency at which the sequence is seen in time-lapse photography. When played at standard speed, time appears to be passing more quickly, and so the video looks to be lapsing.
This allows the ability to produce a fast video of a blooming despite the fact that the blooming takes a lot longer in real-time.
