Options B and D, for sure! Trying to convert strings like 'two' and 'five' to numbers is just asking for trouble.

Hmm, let me think about this. I reckon options B and D are the ones that will give us NaN, right?

Ooh, this is a tricky one! I'm going to go with options B and D, because 'two' and 'five' are definitely not valid numbers.

I think options B and D will output NaN, as they involve converting non-numeric values to numbers.

I'm not sure, but I think option A and C also output NaN because dividing by 0 or a non-numeric value would result in NaN.

I agree with Janae, because parseInt('two') and dividing by 'five' would result in NaN.
