Answer:
The correct answer here would be Austin, Texas
Explanation:
There are a lot of things that make Austin a great place for a large tech company.
To start with Austin is centrally located in the State and has great links with the rest of the country. The local population is young and has some fantastic schools that have supplied a steady stream of high-skilled workforce.
The area also has very affordable housing compared to other larger cities such as Houston or LA.
Add to this, some great weather year round and it's not hard to understand why over 50 of America's fortune 500 companies are headquartered in the city.
