[单选题]
The circuit below cona :d.di+h3dt)lbyr1j sists of a cell and two identical resistori2mzyx 03kgwr/t 1yqc/; hn 4js in parallel, with an ideal ammeter in one of the branches. The current in t/1/h yxjc4 zk0g 2yiwm qtnr;3his branch is $I_1$​ and the current in the other branch is $I_2$​.


If the ideal ammeter is replaced by a real ammeter, what will be the effect on currents $I_1$​ and $I_2​$?

A. $I_1$Decreases; $I_2​$Decreases
B. $I_1$Increases; $I_2​$Stays the same
C. $I_1$Decreases; $I_2​$Increases
D. $I_1$Decreases; $I_2​$Stays the same
