I just edited: Let $f$ be a non-constant entire function such that $\left \lvert f(z) \right\lvert=1$ for every $z$ with $\left \lvert z \right\lvert=1$.
In the question there is a list of options numbered with (a) and (b) and so on. I wanted to put it in a nicer list, but how do you make an ordered list with letters instead of numbers?
If this is not possible, I would suggest that this be made possible.
Edit: I might not have been clear enough: When I edit I want to stay near to the original formatting and wording and change only what I think is needed. I have seen some questions lately where one has to choose between some options (a), (b), (c), and (d), and I just wanted to put that in a list like
with (a), (b), (c), (d) instead of 1,2,3,4. But the only way I can figure out how to do it is by making a bullet point list:
- (a) Option
- (b) Option
- (c) Option
- (d) Option
But I don't like the bullets. The question is whether there is a "pre-formatted" way to do this?
