Answer: D. None of the penalties apply to this return.
Step-by-step explanation:
Marilyn filed her tax return on April 15 which was the deadline for filing in 2020 until it was moved to the 15th of July 2020 on account of the ongoing pandemic. She also attached a cheque for the payment of the tax liability she owed. She filed on time and paid her liability therefore none of the penalties are applicable to her.
