Explanation

The primary purpose of a code review is a collaborative team process to identify defects, logic errors, security vulnerabilities, style violations, and areas for improvement before code is merged. It is inherently a team activity - peers examine each other's work and discuss findings, which also facilitates knowledge sharing. Choice B (detect logical errors) describes only one subset of what code reviews catch. Choice C (ensure all code is checked in simultaneously) is not a purpose of code reviews. Choice D (provide technical lead visibility) is a side effect, not the main purpose. The defining characteristic of a code review is the collaborative identification and discussion of issues.
