Answer OPTION: B) a, b, ReferenceError
Explanation:
The code defines an object obj with properties a and b.
The for...in loop is used to iterate over the enumerable properties of obj. In each iteration, the property name is logged to the console.
The loop will iterate through the properties a and b and log their names: a and b.
After the loop, when console.log(prop) is called, it throws a ReferenceError because prop is not accessible outside the loop.
This is because const creates block-level scope, and the variable prop is scoped to the for loop.
Therefore, trying to access prop outside the loop results in a ReferenceError.
