Consider consecutive processes A$-$B$-$C$,$ where process A has a capacity of $35$ units per hour, process B has a capacity of $20$ units per hour, and process $C$ has a capacity of $30$ units per hour. Following TOC logic, where would an operations manager want any inventory?

in front of process $A$

in front of process B

in front of process $C$
