Source of finance

Sir in an exam question, it was asked to describe three ways to finance a business and state their advantages and disadvantages . In your lecture, you spoke about only two methods such Debt and Equity. You mentioned the short term finance such as bank overdraft, working capital, lease as short term finance etc while long term finance debt such as Bonds or debenture or loan note. For Equity you spoke about share capital (ordinary share), preference share and venture capital. My question now is, according to question above , will i be wrong if i mentioned loan note, equity and lease financing and state their advantages and disadvantages?
