B Correct answer
Explanation

Machine-independent optimization in compiler design refers to optimizations that can be applied to the intermediate code representation rather than being tied to a specific machine architecture. This involves analyzing and transforming code to create more efficient execution patterns without targeting any particular processor, often through techniques like creating optimal intermediate representations or improving algorithmic efficiency at the code structure level.
