Final answer:
Amazon CodeGuru Reviewer Security Detector is a tool for detecting security vulnerabilities in code, providing recommendations for fixing them, and is part of the Amazon CodeGuru suite.
Step-by-step explanation:
The correct answer to the question is (a) A tool for detecting security vulnerabilities in code. Amazon CodeGuru Reviewer Security Detector is part of the Amazon CodeGuru suite, which is a service designed to improve the quality and security of code. It specifically scans your code for common security vulnerabilities and provides recommendations on how to fix them. While it is capable of generating code reviews for best practices and detecting code issues, its Security Detector feature is dedicated to identifying and helping mitigate security risks.
As a security tool, it is not primarily used for profiling code performance (option b), nor is it a feature within CodeGuru Profiler (option c), which is actually a separate tool within the Amazon CodeGuru suite designed for analyzing the performance of your applications. Additionally, while Amazon CodeGuru Reviewer does assist with code reviews (option d), the Security Detector specifically refers to the security aspect of the review process.
