Wait, are we supposed to be creating fat arrow functions or just regular arrow functions? I'm getting a little confused over here...

D is a no-go, my friend. The parameters need to be either a single variable or enclosed in parentheses, not just a list of variables.

Haha, option B with the empty array as the parameter? What is this, a function that doesn't take any input? Sounds like a joke to me.

I'm not sure about option A. Does the single parameter really need the parentheses? I thought arrow functions with a single parameter can omit them.

Option A is incorrect. Arrow functions with a single parameter can omit the parentheses.

I'm not sure about option D, I think it should be lowercase x, y, z instead of uppercase.

Option E looks good to me! The parentheses around the parameters are a must for arrow functions with multiple parameters.
