What act might Kareem be found guilty of by the Commission for managing earnest money inappropriately?

B is the correct answer because commingling client funds with personal funds is a serious violation of real estate laws and regulations. When a broker or agent mixes their own personal funds with clients' earnest money, it creates a risk of misappropriation and can lead to a loss of the clients' money. Regulatory bodies require that earnest money be held in a separate trust or escrow account to protect clients and ensure that their funds are used only for their intended purpose. This practice helps maintain transparency and trust in the handling of financial transactions within real estate.

In contrast, misrepresentation of funds typically deals with false information or statements regarding financials, while failing to deposit money properly may involve an issue with timing rather than the handling of funds. Withholding funds from brokers may pertain to a different area of breach related to commission agreements but does not cover the specific act of mismanagement of earnest money. Thus, option B stands out as the clear and significant violation related to the mismanagement of earnest money.
