Answer 1

The correct answer is option 1.

Transfer function

The transfer function is used to describe networks that have at least two ports.
A transfer function represents the relationship between the output signal of a control system and the input signal, for all possible input values.
The transfer function of a system is defined as the ratio of the Laplace transform of output to the Laplace transform of input where all the initial conditions are zero.

Hence, statement B is true.
