Consider the following days and arrange them in chronological order:1.World Health Day2.National Maritime Day3.World Athletics Day4.World Red Cross DaySelect the correct answer from the codes given below:

1. A

   4, 2, 3, 1

   4, 2, 3, 1. This option lists World Red Cross Day first, which occurs in May, failing to place April events correctly at the start of the chronological sequence.

2. B

   2, 1, 3, 4

   2, 1, 3, 4. This option correctly arranges the days in chronological order starting with National Maritime Day on April 5, followed by World Health Day on April 7, World Athletics Day on May 7, and World Red Cross Day on May 8. National Maritime Day is observed on April 5 to commemorate the maiden voyage of the first Indian-owned ship in 1919. World Health Day is marked on April 7, World Athletics Day falls on May 7, and World Red Cross Day is celebrated annually on May 8, making this precise sequence the correct chronological order.

3. C

   2, 3, 4, 1

   2, 3, 4, 1. This option correctly begins with National Maritime Day on April 5, but places World Athletics Day before World Health Day, disrupting the correct date sequence.

4. D

   3, 2, 1, 4

   3, 2, 1, 4. This option places World Athletics Day first, which is incorrect since it occurs in May, whereas National Maritime Day and World Health Day occur in April.

Summary. Official key is (b) 2, 1, 3, 4. To determine the correct chronological order, we examine the dates of each event: National Maritime Day is on April 5, World Health Day is on April 7, World Athletics Day is on May 7, and World Red Cross Day is on May 8. A common mistake is confusing the dates of World Health Day and National Maritime Day, or mixing up the May observances. Arranging these dates from earliest to latest yields April 5, April 7, May 7, and May 8. Therefore, option (b) is the only correct sequence.
