Answer: A
"Throughput measures how much work is done by a system over
a period of time
it measures productivity of the system. In an online
transaction processing system, transactions per second is a
throughput index. Response time is defined as the length of
time that elapsed between submission of an input and receipt
of the first character of output in an online system.
Turnaround time is the length of time that elapsed between
submission of a job and receipt of a completed output. It is
a measure of timeliness in a batch system. The percentage of
time that the system is available for processing is called
uptime or a reliability index
thus, this is not the correct answer."
