The correct option is B within
The preposition ‘on’ is used to indicate a day or date. The given sentence indicates a duration or time period for the shipping of the albums. Therefore option B is incorrect. The preposition ‘within’ indicates that an action is set to happen anytime inside a particular period of time. In the sentence, the album would reach the people who ordered it inside the time frame of 10 days. On the other hand, ‘from’ and ‘to’ are generally used to denote the beginning or the end of a period. In the given sentence the focus is on the span of 10 days and doesn’t focus on the beginning or end. Hence option A is correct, while options C and D are incorrect.
