RVO stands for Return Value Optimization, a compiler optimization that avoids creating temporary objects by using the return value of a function directly. This can result in improved performance as it avoids unnecessary object copying operations. The other options are incorrect because they do not accurately describe what RVO stands for. A) Relative Value Optimization is not a commonly used term and does not describe a specific compiler optimization. C) Runtime Value Optimization is also not a commonly used term and does not specifically refer to the optimization technique used in operator overloading. D) Reference Value Operation is not a commonly used term and does not accurately describe the concept of return value optimization.
