49.
An open loop system has a forward path transfer function (42.25)/s(s + 6.5). The unit step response of the system starting from rest will have its maximum value at a time equal to
Answer: Option
Explanation:
Unit step response is 
Taking inverse transform, the time domain response is - 1 + 6.5t + e-6-5t. It reaches maximum value at t = infinity.

In the solution we are taking the wrong transfer function as the transfer function given in the question is different.
By taking the transfer function given in the question-answer will be option B i.e. 0.56 sec.
Hint: maximum value can be reached at peak time so calculate using peak time formula.
