Answer:
B) Trusts (except those that are exempt)
Step-by-step explanation:
The only three entities that are allowed to select a fiscal year are: estates, C corporations and tax exempt entities.
Trusts, along with partnerships, S corporations and personal service corporations mus use the calendar year as their taxable period or the tax year of their owners. Some trusts can change to a different calendar year if they can establish a business purpose for doing so.
