O A. 18 V
O B. 32 V
O C.21 V
O D. 94 V

94 V

Explanation:

Here we don't have the figure showing the circuit and how the resistors are connected: therefore, we have to make some assumptions.

Here we will assume that the three resistors are connected in series: this means that they are connected along the same branch, and therefore, the current flowing through them is the same.

As a result, the total voltage drop across some resistors in series is given by the sum of the voltage drops on each resistor.

Therefore, for three resistors in series

Where here we have:

is the voltage drop on the 1st resistor

is the voltage drop on the 2nd resistor

is the voltage drop on the 3rd resistor

Substituting into the equation, we find:
