Which of the following locations is not home to a US military base or establishment?

The selection of India as the location not home to a US military base or establishment is accurate because, unlike Puerto Rico, Saudi Arabia, and Turkey, India does not host a formal US military base. While the United States and India have collaborated on defense and security matters, including joint exercises and logistical agreements, there is no permanent US military installation in India.

In contrast, Puerto Rico, as a US territory, has significant military presence with several bases; Saudi Arabia has a historical partnership with the US that includes military installations; and Turkey has been a critical NATO ally that hosts several US military bases. The lack of a permanent US military base in India underscores the distinct nature of US-India military relations, which are more focused on cooperation rather than establishing a military footprint.
