The correct answer is 100.

Step-by-step Explanation:

Step 1: Extract data for Airline D from the given table
From the table provided in the question, we have the following data for Airline D:
• Total number of aircrafts in Airline D = 18
• Average number of passengers in each aircraft = 10
• Ratio of Domestic passengers to International passengers = 5 : 4

Step 2: Calculate the total number of passengers in Airline D
The total number of passengers is equal to the total number of aircrafts multiplied by the average number of passengers per aircraft:

Total passengers = 18 × 10 = 180

Step 3: Calculate the total number of domestic passengers in Airline D
The passengers are divided between Domestic and International in the ratio 5 : 4.
Sum of the ratio terms = 5 + 4 = 9 parts.

Out of these 9 total parts, 5 parts correspond to domestic passengers.

Total domestic passengers = 5 9 × 180

Total domestic passengers = 5 × 20 = 100

Thus, the total number of domestic passengers in aircrafts of Airline D is 100.
