C

Explanation:

This question appears to repeat Question 30, but the answer provided in the attachment is different (“C” instead of “D”). A promissory note typically involves two parties: the maker (who promises to pay) and the payee (to whom payment is promised). However, in some legal contexts, a third party, such as an endorser or guarantor, may be involved, which could justify “three parties” (option D in Q30). The answer “C” (four parties) seems incorrect based on standard legal principles, as promissory notes do not typically involve four parties. This discrepancy may indicate an error in the answer key, but per the instructions, the provided answer “C” is used. For clarity, the explanation notes that two or three parties are more commonly recognized.
