In the context of the Old Testament sacrificial system, what is the precise distinction between a 'burnt offering' (olah) and a 'sin offering' (hattat)?

A A burnt offering was exclusively for unintentional sins, while a sin offering covered intentional transgressions. B A burnt offering was entirely consumed on the altar, signifying complete devotion, while a sin offering had portions reserved for the priests. C A burnt offering involved only male animals, while a sin offering could include both male and female animals depending on the offerer's status. D A burnt offering was offered daily, while a sin offering was reserved for specific festivals and high holy days.
