Respuesta correcta
- do not have to bring
- don't have to bring
- don’t have to bring
Explicación
Do not have to bring says that hikers are free to bring a map but are under no obligation to do so. Must not bring would prohibit personal maps and contradict the premise that bringing one is optional.
