The question asks us to observe and compare the time it takes for a five-rupee coin, a feather of a sparrow bird, and a mango to reach the bottom when dropped simultaneously from the same height in a vacuum.

Option 1 states that the time taken by the coin (t1) is greater than the time taken by the feather (t2), and the time taken by the feather (t2) is greater than the time taken by the mango (t3). This option implies that the coin takes the longest time, followed by the feather, and then the mango.

Option 2 states that the time taken by the coin (t1) is greater than the time taken by the mango (t3), and the time taken by the mango (t3) is greater than the time taken by the feather (t2). This option implies that the coin takes the longest time, followed by the mango, and then the feather.

Option 3 states that the time taken by the mango (t3) is greater than the time taken by the coin (t1), and the time taken by the coin (t1) is greater than the time taken by the feather (t2). This option implies that the mango takes the longest time,
