What will be logged when executing the following code?

• A. Hello
• B. Hey!
• C. undefined
• D. ReferenceError

Answer: (A)

The code likely involves a console log of a variable or a function invocation that, when executed in a JavaScript context, outputs "Hello". In JavaScript, when a string or variable is logged using console.log, it displays that value in the console. If the code consists of straightforward logging, such as `console.log("Hello");`, it directly logs "Hello" to the console, which corresponds to the correct answer. Understanding that variables or functions can also be initialized or called in various contexts helps clarify why "Hello" is the expected output. Options like undefined or ReferenceError would typically arise from trying to log something that hasn't been defined or attempting to access variables that don't exist at the time of execution. However, in this case, it's clear that the execution leads to the valid output of "Hello".
