What should be done to fix the syntax error in line 8?

The choice to add a semicolon at the end of line 8 addresses a common syntax requirement in many programming languages, such as C or C++. In these languages, statements must be terminated with a semicolon to indicate the end of that statement. When a semicolon is missing, the compiler cannot correctly interpret where one statement ends and another begins, leading to a syntax error.

In line 8, if there is indeed a statement that should conclude with a semicolon, adding it will clarify the end of that instruction, allowing the code to compile successfully. Syntax errors often stem from small oversights like this, which can disrupt the entire program's execution.

The other options do not necessarily contribute to resolving a syntax issue in the context of terminating statements or aligning with the rules of the programming language being used. For instance, changing printf to Printf would not fix a missing semicolon but instead could lead to a different error depending on whether Printf is defined elsewhere. Removing a line may inadvertently eliminate necessary code, and adding curly brackets may not have any bearing on the statement needing a semicolon if the statement in line 8 is correctly formed but simply lacks a proper ending.
