Final answer:
The question is regarding Alfred's tax filing status. Alfred is single and supports a friend in another state. He does not likely qualify as Head of Household; therefore, his filing status would most likely be Single.
Step-by-step explanation:
The question is asking for the correct filing status for Alfred, who is unmarried and supports a friend living in a different state. In the context of U.S. federal income tax, filing status determines the rate at which income is taxed. The common filing statuses include Single, Married Filing Jointly, Married Filing Separately, Head of Household, and Qualifying Widow(er) with Dependent Child.
Given the information that Alfred is single and supports his friend, he may potentially qualify for the Head of Household status if certain conditions are met, such as the friend being a qualifying person and meeting the requirements for a dependent. However, since the friend does not live with him, it's unlikely that Alfred's friend would qualify as a dependent. Typically, the friend would need to be a relative for the support to allow for the Head of Household status. Therefore, Alfred's most likely filing status is Single.
