The answer to this question is "15 line".

Explanation:

A function is a block of ordered, portable code used to perform a single, connected operation. The syntax of function declaration can be given as:

Syntax:

returntype functionName (parameter1, parameter2); / /function prototype

or declaration

returntype functionName (parameter1, parameter2) / /function definition or header of the function

{

//function body.

//function implementation

//return value;

}

In the given question the header of the showDub function is on line 15.

That's why the answer to this question is "15 line".
