The command lscpu stands for 'list CPU' and is used to display information about the CPU architecture. It shows detailed and specific information including the number of CPUs, cores, threads, CPU family, and architecture. This is crucial information when diagnosing systems for CPU-related performance issues. The other options, while they may relate to system information, do not provide the detailed CPU architecture information that lscpu does.
