What will console.log(undefined) give during the execution of checkAge({ age: 18 })?

• A. You are an adult!
• B. You are still an adult.
• C. Hmm.. You don't have an age I guess
• D. ReferenceError

Answer: (C)

In the context of the function call checkAge({ age: 18 }), when the code attempts to log `undefined`, it indicates that the function is likely trying to access a property or variable that doesn't exist within the provided object or its context. If the function is attempting to reference a property named `age`, but for some reason, it's being referenced as `undefined`, the output would communicate that the age value is not available. For instance, if there's a check within the `checkAge` function that evaluates the age property and it finds that the passed object does not provide a valid `age` property or the reference is somehow incorrect, it would lead to this scenario. The console would print the string indicating the absence of an age value, hence outputting "Hmm.. You don't have an age I guess". This explains the correct outcome of the console logging while emphasizing the potential misinterpretation of data passed to the function. This aligns with the idea that if the age property is not accessible or was not defined correctly, it would reflect as `undefined` in the console output.
