A person standing on the floor of an elevator drops a coin. The coin reaches the floor in time \( t_1 \) if the elevator is at rest and in time \( t_2 \) if the elevator is moving uniformly. Then

1. A
   \( t_1 = t_2 \)
2. B
   \( t_1 < t_2 \text{ or } t_1 > t_2 \text{ depending upon whether the lift is going up or down} \)
3. C
   \( t_1 < t_2 \)
4. D
   \( t_1 > t_2 \)
