In Texas, which barrier island features the Padre Island National Seashore?

Padre Island National Seashore is located on Padre Island, which is the longest barrier island in the world, stretching along the southern coast of Texas. This area is significant not only for its natural beauty but also for its unique ecosystems and wildlife habitats, making it a designated national seashore. The park offers opportunities for various recreational activities while also serving as a vital area for environmental preservation.

Other choices, while they are indeed named islands in Texas, do not host the Padre Island National Seashore. Galveston Island is known for its beaches and historic sites, Mustang Island is a smaller barrier island but does not have the national seashore designation, and Corpus Christi Island is more of a general term that refers to the city rather than a specific island. Thus, it is clear that the correct answer is Padre Island due to its established status as the home of the Padre Island National Seashore.
