I'm hungry just looking at this code. I wonder if there's a function that can add some snacks to the mix?

Aha, Option D looks like the winner! Currying is the way to go here, nice and concise.

Option C is interesting, but I'm not sure about the use of 'num2' when it's not defined. Hmm, curious.

Option B is a no-go, it's missing a parameter. How can we add without a second number?

Yeah, option B is definitely not the right choice. We need that second parameter to add the numbers together.

Option A looks good, but why do we need a nested function? Seems a bit overkill for such a simple task.

Nested functions can help with code organization and readability.

Option A is more flexible and allows for currying, which can be useful in certain situations.

I think option A and D are correct because they both return a function that adds two numbers.

I agree with Annett, option A and D both return the sum of two numbers.
