The expression for efficiency when a & b are two constants corresponding to alpha & beta and c corresponds to gamma, is?

A. Efficiency = 1 ((b<sup>2</sup>))/((b + c)(a + b c)))
B. Efficiency = 1 + ((b<sup>2</sup>))/((b + c)(a + b c)))
C. Efficiency = ((b<sup>2</sup>))/((b + c)(a + b c)))
D. Efficiency = 1 / ((b<sup>2</sup>))/((b + c)(a + b c)))
Answer» B. Efficiency = 1 + ((b<sup>2</sup>))/((b + c)(a + b c)))
