Ooh, I love a good system diagnosis! B) free is the obvious choice here. Although, I might throw in a 'vmstat' just for fun. Spice things up, you know?

Don't forget to also check 'top' command for CPU usage.

B) free is the way to go! Although, I'd probably use 'top' to see what's hogging the CPU too. Gotta cover all the bases, you know?

D) lop? Really? That's not even a real command! I'm going with C) uptime to check the system's load average.
