Form 1065 is specifically designed for partnerships, which is why the correct answer is the type of business entity required to file it. Partnerships, as defined by the IRS, are entities where two or more individuals join together to operate a business and share profits. This form serves as an informational return, reporting the partnership's income, deductions, gains, and losses for the year, even though the partnership itself is not subject to income tax. Instead, the income "passes through" to the individual partners who report their share on their personal tax returns.

The other types of business entities do not file Form 1065 for various reasons related to their legal structure and tax treatment. Sole proprietorships file a Schedule C attached to the owner's individual return, while corporations have different forms to submit, such as Form 1120. Limited Liability Companies (LLCs), depending on their tax classification, may file Form 1065 if they are treated as partnerships for tax purposes, but if they choose to be taxed as corporations, they would file the corporate form instead. Thus, the unique characteristic of partnerships necessitates the requirement to file Form 1065.
