Final answer:
The left side of a T-account is known as the debit side, which typically represents a company's assets.
Step-by-step explanation:
The account title is shown at the top of a T-account, which is used to represent the financial standing of a firm or bank. The left side of the T-account is referred to as the debit side, which corresponds to the answer choice d) Debit side in the student's question, and it generally includes the company's assets. On the other hand, the right side of the T-account is called the credit side and typically lists the firm's liabilities and net worth. The balance sheet, shaped like a T, illustrates a company's assets on one side and its liabilities and net worth on the other, ensuring that the total assets always equal the total liabilities and net worth.
