The transfer function of the system shown below is

(a) \(\frac{\mathrm{Q}}{\mathrm{R}}=\frac{\mathrm{ABC}}{1+\mathrm{ABC}}\)
(b) \(\frac{\mathrm{Q}}{\mathrm{R}}=\frac{\mathrm{A}+\mathrm{B}+\mathrm{C}}{1+\mathrm{AB}+\mathrm{AC}}\)
(c) \(\frac{\mathrm{Q}}{\mathrm{R}}=\frac{\mathrm{AB}+\mathrm{AC}}{\mathrm{ABC}}\)
(d) \(\frac{\mathrm{Q}}{\mathrm{R}}=\frac{\mathrm{AB}+\mathrm{AC}}{1+\mathrm{AB}+\mathrm{AC}}\)
