Option 1 states that the news will be heard in Dhaka at 7:45 p.m. on Monday. To understand if this is the correct answer, we need to consider the time difference between London (the source of the broadcast) and Dhaka.

Dhaka is located at 90° E, while London is at 0° E. Since Dhaka is east of London, it is ahead in time. Each 15° of longitude represents a time zone difference of approximately 1 hour. Therefore, the time difference between London and Dhaka is 90°/15° = 6 hours.

Given that the news is broadcast from London at 1:45 p.m., we need to add the time difference of 6 hours to determine when it will be heard in Dhaka. Adding 6 hours to 1:45 p.m. gives us 7:45 p.m.

Therefore, option 1 is correct, and the news will be heard in Dhaka at 7:45 p.m. on Monday.

Note: It is important to check the time difference before reaching a conclusion as different countries may have different time zones.
