Singapore is 3 hours ahead of Chennai and New Jersey is 11 hours behin...
To solve this problem, we need to consider the time differences between Singapore, Chennai, and New Jersey and calculate the time it takes for the flight to reach New Jersey.

Given Information:
- Singapore is 3 hours ahead of Chennai.
- New Jersey is 11 hours behind India.
- The flight from Chennai to Singapore took off at 6 a.m. and reached Singapore at 12 noon.
- The distance between Chennai and New Jersey is exactly 4 times the distance between Chennai and Singapore.
- A flight with the same speed takes off from Chennai at 9 a.m.

Step 1: Calculate the time difference between Chennai and Singapore
Since Singapore is 3 hours ahead of Chennai, the flight from Chennai to Singapore took 6 hours (12 noon - 6 a.m.).

Step 2: Calculate the time difference between New Jersey and Singapore
Since New Jersey is 11 hours behind India, and Singapore is 3 hours ahead of Chennai, we can infer that New Jersey is 8 hours behind Chennai (11 - 3).

Step 3: Calculate the time taken to travel from Chennai to New Jersey
Since the distance between Chennai and New Jersey is exactly 4 times the distance between Chennai and Singapore, the time taken to travel from Chennai to New Jersey will also be 4 times the time taken to travel from Chennai to Singapore.

The flight from Chennai to Singapore took 6 hours, so the flight from Chennai to New Jersey will take 4 * 6 = 24 hours.

Step 4: Calculate the local time in New Jersey when the flight takes off from Chennai at 9 a.m.
If the flight takes off from Chennai at 9 a.m., it will reach New Jersey 24 hours later. Therefore, the local time in New Jersey will be 9 a.m. + 24 hours = 9 a.m. the next day.

Therefore, the flight, which takes off from Chennai at 9 a.m., will reach New Jersey at its local time at 9 a.m. the next day.

Hence, the correct answer is option D) 10 a.m.
