Explanation:
Distance travelled by car during reaction time

The car stopped before hitting the animal by 
Distance travelled during deceleration is 
Hence by 
We have

Option C is the correct answer
I think the answer is D. Bicycle
Bodies in space traveled in circles.
The planets revolved around the Earth.
The wires would remain attracted to each other.
Option D.
Explanation:
It is known that magnetic flux will be generated in conductors with varying emf. So when current is flowing in two parallel conductors, the magnetic flux will be generated in those wires. If the current is flowing in same direction in both the wires, then the magnetic flux will be generated towards inside and outside the wires. Thus, the wire will get attracted to each other till the time the current is flowing in the same direction in both the wires. So if the current flow in each wire was reversed at the same time, then the wire would remain attracted to each other.
