Assuming all other conditions for plotting control charts to be valid, which condition holds TRUE for plotting I-MR Charts?

When you can collect only one observation per day
When it is not feasible to use averages chart for process control
When within-subgroup variation is to small relative to batch-batch variation
All of the above
