Preview: Explanations
1."must"(a)
'Must' expresses obligation — it's compulsory, so it's not a choice. 'Can' and 'may' would express permission, which doesn't match 'compulsory'.
2."can"(b)
'Can' expresses permission — the coupon allows you to do something. It's not an obligation (must/have to) or a prohibition (mustn't).
3."mustn't"(c)
'Mustn't' expresses prohibition — something is strictly forbidden. 'Don't have to' means it's not necessary (no obligation), which is very different.
4."have to"(d)
'Have to' expresses obligation — there is a deadline, so it's required. 'Can' and 'may' express permission, not obligation.
5."may"(a)
'May' gives permission — it's optional ('if they want to'). 'Must' and 'have to' would make it an obligation.
