Nobody must expect to be rich without hard work

[Enjoyenglish]

Hello. It says to write the second sentence so that it has a similar meaning to the first.
- Nobody must expect to be rich without hard work.
=> Unless ...................................................................
a- Unless people work hard, they won't expect to be rich.
b- Unless people work hard, they won't be rich.
Are A and B all right, please?

There are only two options, so ask 'Are A and B both right, please?'

No. B makes no mention of people's expectations.

a- Unless people work hard, they won't expect to be rich.

"Won't" doesn't work in the above. Use "mustn't", "cannot" or "shouldn't."
