The correct answer is C — HTTP interceptor.

According to WGU Cybersecurity Architecture and Engineering (KFO1 / D488), an HTTP interceptor is a tool or method used to capture, inspect, and manipulate HTTP/S traffic between aclient and server. It allows testers to identify security vulnerabilities such as improper input validation, session management flaws, and exposure of sensitive data.

A Bastion scanner (A) is not a standard tool for traffic inspection. Port scanners (B) check for open ports but do not inspect HTTP traffic content. Domain interceptors (D) are not a recognized testing tool in this context.

Reference Extract from Study Guide:

"HTTP interceptors allow for the inspection and manipulation of web traffic, helping to identify application vulnerabilities prior to deployment."
