BYOND lists are 1-based indexes, and not 0, so when you put that "0=" there you're breaking things pretty bad. You don't need the "[num]=" part at all, actually. Just the text.

You can use pick() to pick a random item from the list.

List indices start at 1, not 0. You also don't need to specify the index for each item in the list.
var list/responses = list("A", "B", "C")

Click()
    // output one of the responses randomly
    // response index is a number from 1 to the number of items in the list
    usr << responses[rand(1, length(responses))]

    // the above is equivalent to this:
    usr << pick(responses)
