1."mustn't"(d)
'Mustn't' means it is prohibited — you are not allowed to do it. Smoking in a hospital is forbidden by law.
2."don't have to"(b)
'Don't have to' means it is not necessary. The concert is free, so buying a ticket is optional, not forbidden.

'Mustn't' = prohibition. Using phones during an exam is forbidden and has serious consequences.
