Which of the following does not contain a syntax error? a. system. out. println("hello world! "); b. system. out. println(hello world! ); c. system. out. println('hello world! '): d. system. out. println("hello world! ");

a. System.out.println("Hello world!");

d. System.out.println("Hello world!");

Explanation:

Option b doesn't have the apostrophe within the bracket so it's incorrect.

Option c doesn't have the correct double apostrophe within the bracket so it's incorrect. Running option b and c code will not compile properly and give an error.

what are the answer choices?
