Because format_message is declared to take (name: str, font_size: int) and return a str, the program must pass a string for name and an int for font_size, and capture the returned string in message.

1) Relevant knowledge points and concepts
- input() always returns a string. So font_size = input('Enter a font size: ') yields a string like '12', not the integer 12.
- The function signature format_message(name: str, font_size: int) indicates the second argument should be an integer.
- The function returns a string, so the caller must assign that return value to message before printing.

2) Step-by-step reasoning
- After line 12: name is a string (e.g., "Alex").
- After line 13: font_size is a string (e.g., "14").
- We must convert font_size from string to int: int(font_size) turns "14" into 14.
- Call format_message with the original name and the converted font size: format_message(name, int(font_size)).
- Assign the result to message so print(message) on line 15 prints the formatted text.

3) Intermediate steps (conversions)
- Example: name = input(...) -> "Alex"
- font_size = input(...) -> "14"
- int(font_size) -> 14
- message = format_message("Alex", 14) -> returns formatted string, e.g., "Alex (size 14)"

4) Why the correct answer is correct
- It matches the declared parameter types (str, int) and stores the function’s return value in message before printing. This produces the desired formatted output.

5) Why the other options are incorrect
- Option 1: message = format_message(name, font_size) passes a string for font_size; that contradicts the signature and will fail if the function expects numeric behavior.
- Option 2: message = format_message(int(name), float(font_size)) converts name to int (invalid for typical names) and converts font_size to float rather than int; both misuse types.
- Option 3: format_message(name, int(font_size), message) provides three arguments though the function expects two, and message isn’t defined yet.

6) Conclusion
The correct missing line is:
14    message = format_message(name, int(font_size))
This matches the provided answer.
