Working link…same as other balloon question. See section titled: Memory Performance Enhancement Advice

If all the symptoms are observed withing a VM (high % usage of internal memory and frequent internal swapping), they are the classic indicators of insufficient memory configured for this VM, thus making all available answers N/A.
A,B,C would help only if the described symptoms pertain to the ESX host where the VM is running.
