The correct answer is: The voltage drop across 
is 45V.
Explanation:
First you need to find the total current of the circuit, which is:
According to Ohm's law:
V = I * R
I = V/R --- (1)
Where
R = Total Equivalent resistance of the circuit
V = Total Voltage = 90V
I -= Total Current
First let us find the equivalent resistance:
Now plug in the values in (1):
(1) => I = 90/30 = 3A
Now that we have current of the circuit, we can now find the voltage drop across = 15 ohms using:
Where
is the voltage drop across resistor 5;
