Answer:
Expense must be recognized in July
Explanation:
The reason is that the expense must be recognized in the month in which the supplies are used because the accrual concept says that the expenses must be realized when they are incurred. Incurred means that the consideration received has been used. For example if I pay the telecommunication network in June to give 4G internet and the services are delivered in the month July then the expenses will be realized in the month in which the services were used and that is July for internet facilities. So in this case the supplies are used in the month of July which is in-accordance with the accrual concept.
