Answer: C. The drone is on the ground at 0 and 4 seconds.
Step-by-step explanation:
Here the function that shows the height of the drone,
Where t is the time in seconds.
Since, the drone is ground when, h(t) = 0
(by subtracting 64 from both sides 64)
(dividing both sides by -16 )
(by subtracting 4 from both sides)
⇒ t = 0 or t = 4
Thus, Option C is correct.
