3. It is a Greenwich meridian helping in fixing time and date
4. It solves the problem of time and date among the World's nations Correct Answer 1, 2 and 4

The International Date Line (IDL) is an important concept in geography that helps define where one calendar day ends and the next begins. Let's analyze the given options:

Statement 1: It is a longitude of 180°.
Correct. The International Date Line is often positioned along the 180° meridian of longitude.

Statement 2: It is determined by 180° longitude but is not a straight line.
Correct. This statement is accurate. The International Date Line is not a straight line due to adjustments made to avoid dividing land areas and nations.

Statement 3: It is a Greenwich meridian helping in fixing time and date.
Incorrect. The International Date Line is not a Greenwich meridian. It serves a distinct purpose of separating different calendar days.

Statement 4: It solves the problem of time and date among the World's nations.
Correct. The International Date Line indeed helps address the challenge of coordinating time and date differences across the world, ensuring a systematic transition from one day to another.

Based on the explanations provided, the correct options are E: 1, 2, and 4. The International Date Line is a longitude of 180°, determined by 180° longitude but not a straight line, and it helps solve the problem of time and date coordination among different nations.
