Answer:
B. 640,000 bits
Explanation:
From the given question,
The voice line has 24 channels with each having the capacity for 1 telephone conversation with the size of 8 bits and 8, 000 samples/second.
Thus for a 10 seconds clip, the rate = 8 000 × 10
                              = 80 000
The rate is 80 000 samples/second.
The size of the storage in bits = rate ×8 bits
                         = 80 000 × 8
                         = 640 000 bits
Therefore, the size of the storage required for storing the video clip on disk is 640 000 bits.
