What is the first company (alphabetically) in the IT services industry with 5 to 10 locations, headquartered in Texas?

The answer identifies Alert Logic as the first company alphabetically in the IT services industry with 5 to 10 locations and headquartered in Texas. This is correct because when looking at the companies listed, Alert Logic indeed comes before the others in alphabetical order.

Accenture, while recognized as a major player in IT services, is a global company and does not fit the specified location criteria based on the question's parameters. IBM is another large organization that, while it operates extensively in IT services, does not meet the location number specified. Infosys, based in India, operates globally, but does not start with an "A," making it fall lower in the alphabetical ranking.

In this context, Alert Logic meets all the criteria of being an IT services company, meeting the location requirement, and is correctly positioned first alphabetically among the options provided.
