@Thamin.

You are answer is right but, little confusion. Please explain how you gate 5T?

Why the transient response is about 5T only ? I didn't get.

@Thamin.

You'r explained but very confuse. Any way you are only person is tried to answer this question. Thank you.

(please explain me again once to short answer).

If a resistor is connected in series with the capacitor forming an RC circuit, the capacitor will charge up gradually through the resistor until the voltage across the capacitor reaches that of the supply voltage. The time called the transient response, required for this to occur is equivalent to about 5 time constants or 5T. This transient response time T, is measured in terms of T = R x C, in seconds, where R is the value of the resistor in ohms and C is the value of the capacitor in Farads. This then forms the basis of an RC charging circuit were 5T can also be thought of as "5 x RC".
