Explanation

Code review is the practice of having peers examine code before it is merged. Its primary benefit is enforcing consistency - in coding standards, architectural patterns, naming conventions, and design decisions - across a team where multiple developers contribute. Reviews spread knowledge, catch deviations from agreed-upon design patterns, and prevent one-off implementations from fragmenting the codebase. Option A is incorrect - code review actually constrains (not enables) arbitrary design variations. Option C is wrong - reviews promote collaboration, the opposite of isolation. Option D overstates the guarantee; reviews improve security but cannot ensure the entire software is secure.
