C Correct answer
Explanation

The Front Side Bus (FSB) was the primary data path between CPU and memory (Northbridge) in older PC architectures. Its speed dictated how fast data could move between critical components, making it a performance bottleneck. Modern systems use QPI, HyperTransport, and integrated memory controllers instead.
