Final Answer : C, Explanation :   The general voltage divider formula is   E X = ( R X R T ) E T  E_{X}=\left(\frac{R_{X}}{R_{T}}\right) E_{T}  E X ​ = ( R T ​ R X ​ ​ ) E T ​  , which calculates the voltage across a resistor (  R X R_{X} R X ​  ) in a series circuit, where   E T E_{T} E T ​   is the total voltage and   R T R_{T} R T ​   is the total resistance.
