Consider a $6-$stage pipeline with stage delays of $35,40,28,42,30$ and $38$ nanoseconds respectively $($including the latch delays$).$ It is required to process $5000$ data items in the pipeline. What will be the minimum time required to process the data items?

a$)1065$ microseconds

b$)210\mathrm{.}2$ microseconds

c$)105\mathrm{.}1$ microseconds

d$)$ None of these.
