man vmstat
vmstat reports virtual memory statistics regarding kernel
thread, virtual memory, disk, trap, and CPU activity.

kthr Report the number of kernel threads in each of the
three following states:

r the number of kernel threads in run queue

b the number of blocked kernel threads that are
waiting for resources I/O, paging, and so
forth

w the number of swapped out lightweight
processes (LWPs) that are waiting for pro-
cessing resources to finish.

So I think A is correct if run queue = active
