If a compiler detects a violation of language rules, it refuses to translate the class to
a.
machine code
b.
a logic error
c.
an application
d.
java

a. machine code

Explanation:

When we code a program, be it in C, C++, Java, etc,..., the role of the compiler is to translate our code to machine code, so it can be executed.

This only happens if we do not violate any of the language rules. Otherwise, there are going to be compilation errors and we will have to fix our code before it is compiled, that is, translated to machine code.

So the correct answer is:

a. machine code
