Concept:
When an object falls freely under gravity, the distance covered by it in each second follows a specific pattern.
Explanation:
First Second:
- In the first second, the distance covered by the object can be calculated using the formula: Distance = 1/2 * g * t^2 (where g is the acceleration due to gravity and t is the time in seconds)
- Let's assume the acceleration due to gravity, g = 10 m/s^2
- Therefore, the distance covered in the first second = 1/2 * 10 * 1^2 = 5 meters
Second Second:
- In the second second, the object continues to accelerate under gravity. The distance covered in the second second can be calculated using the same formula.
- Distance covered in the second second = 1/2 * 10 * 2^2 = 20 meters
Third Second:
- Similarly, the distance covered in the third second can be calculated as:
- Distance covered in the third second = 1/2 * 10 * 3^2 = 45 meters
Ratio:
- The distances covered in the first, second, and third seconds are 5 meters, 20 meters, and 45 meters respectively.
- The ratio of these distances is 5:20:45, which simplifies to 1:4:9.
Therefore, the correct answer is option 'A', with the distances covered by the body in the first, second, and third seconds in the ratio 1:3:5.

Therefore, the correct answer is option 'A', with the distances covered by the body in the first, second, and third seconds in the ratio 1:3:5.
