Three Resistors Connected in Parallel Have the Individual Voltages Labeled $\Delta$

Three resistors connected in parallel have the individual voltages labeled $\Delta$ V₁, $\Delta$ V₂, and $\Delta$ V₃, respectively. Which of the following expresses the total voltage $\Delta$ V_T across the three resistors when connected in this manner?

A) " $\Delta$ V_T = (1/ $\Delta$ V₁ + 1/ $\Delta$ V₂ + 1/ $\Delta$ V₃) "
B) " $\Delta$ V_T = $\Delta$ V₁ + $\Delta$ V₂ + $\Delta$ V₃"
C) " $\Delta$ V_T = (1/ $\Delta$ V₁ + 1/ $\Delta$ V₂ + 1/ $\Delta$ V₃) ^{- 1}"
D) " $\Delta$ V_T = $\Delta$ V₁ = $\Delta$ V₂ = $\Delta$ V₃"
