Final Answer :
B
Explanation :
The total resistance in a series circuit is simply the sum of all resistances (and resistive components) in the circuit. Here, you have two resistors with resistances of 39 Ω and 56 Ω. The capacitive reactances are not resistances and should not be added to the resistances. Therefore, the total resistance is 39 Ω + 56 Ω = 95 Ω.
