Select one of the options below as your answer:

A.
increase; 0.51 amps
B.
increase; 0.72 amps
C.
increase; 3.6 amps
D.
decrease; 0.51 amps
E.
decrease; 0.72 amps

In situation before the another resistor is added:
I=V/R=9/2*5=0,9 A
In situation with added resistor:
I=9/(2*5+7,5)=0,51, so it will decrease and get a finally value of 0.51 A
