there are two different tax rates for profits from selling investments. what determines which tax rate you…

Brief Explanations:

When it comes to capital - gains taxes (taxes on profits from selling investments), the holding period of the investment is a key determinant. Short - term capital gains (for investments held for one year or less) are taxed at ordinary income tax rates. Long - term capital gains (for investments held for more than one year) are taxed at lower rates. The type of investment (A) may have some implications in terms of tax - advantaged accounts etc., but the primary determinant for the basic tax - rate distinction is the holding period. Income (B) can affect the actual amount of tax paid (especially for long - term gains where there are different tax brackets), but it is not the factor that distinguishes between the two main tax - rate categories (short - term vs long - term). Who you sell to (D) generally does not affect the tax rate.

Answer:

C. how long you owned the investment
