An inflow hydrograph is routed through a reservoir to produce an outflow hydrograph. The peak flow of the inflow hydrograph is $P_{I}$ and the time of occurrence of the peak is $t_{I}$. The peak flow of the outflow hydrograph is $P o$ and the time of occurrence of the peak is $t_{o} .$ Which one of the following statements is correct?
(A) $P_{I}<P o$ and $t_{I}<t_{O}$
(B) $P_{I}<P_{O}$ and $t_{I}>t_{O}$
(C) $P_{I}>P o$ and $t_{I}<t_{O}$
(D) $P_{I}>P_{O}$ and $t_{I}>t_{O}$
