Function bodies do not execute when the function is defined. They execute only when the function is called.

First, Python executes:

print("Start")

So the first output is $\texttt{Start}$.

Then $\texttt{second()}$ is called. Inside $\texttt{second()}$, Python first prints $\texttt{B}$.

Then $\texttt{first()}$ is called, so Python enters $\texttt{first()}$ and prints $\texttt{A}$.

After $\texttt{first()}$ finishes, control returns to $\texttt{second()}$, and $\texttt{C}$ is printed.

Finally, after $\texttt{second()}$ finishes, Python prints $\texttt{End}$.

Therefore, the output is:

Start
B
A
C
End

Correct Option: B
