Answer:
Step-by-step explanation:
The correct answer is C. The aeronautics industry.
The growth of military fields and commercial airports across Texas can be attributed to the development and expansion of the aeronautics industry. This industry involves the design, manufacturing, and operation of aircraft and spacecraft.
Texas has played a significant role in the aeronautics industry, particularly through the establishment of military bases and the presence of major aerospace companies. For example, Fort Worth in Texas is home to the Lockheed Martin Aeronautics Company, which produces military aircraft such as the F-35 Lightning II. Additionally, Houston is known for its role in the space industry, with the NASA Johnson Space Center located there.
The growth of military fields and commercial airports in Texas is a result of the state's involvement in the aeronautics industry. Military fields are essential for training pilots, testing aircraft, and conducting military operations. Commercial airports, on the other hand, facilitate the transportation of goods and passengers via airplanes.
In conclusion, the aeronautics industry has led to the growth of military fields and commercial airports across Texas, making it a significant contributor to the state's economy and infrastructure.
