For the given block diagram, the transfer function \(\frac{{C\left( s \right)}}{{E\left( s \right)}}\) if N(s) = 0 is
1
\(\frac{{10\left( {s + 5} \right)}}{{{s^2} + 6s - 30}}\)
2
\(\frac{{10\left( {s + 7} \right)}}{{{s^2} + 6s - 30}}\)
3
\(\frac{{5\left( {s + 7} \right)}}{{{s^2} + 4s - 20}}\)
4
\(\frac{{5\left( {s + 5} \right)}}{{{s^2} + 4s - 20}}\)
