Answer 1

Right choice is (a) setTimeout(function() { console.log(“Hello World”); }, 1000); To explain I would say: SetTimeout function is used to hold the execution of the code with the required amount of time. The argument of the setTimeout includes the function which is to be executed followed by the time after which the code is to be executed.
