According to the given conditionDenominator = 7 + C [C > -7]
\begin{array}{*{20}{c}} {{\text{Denominator}} = }&{{\text{Greator number}}}&{}&{{\text{Smaller number}}} \\ {}&{\left( {7 + C - 4} \right)}& \times &{\left( {7 + C - 4 - 2} \right)} \end{array}
Equation
By putting value according to option
C = -2 for minimum value
= -1/5
