Identifying long-term finance sources for limited companies Steps:

• Define long-term sources as finance obtained for over one year or permanently, providing stable funding without short-term repayment pressure.
• Evaluate each option by checking if all items qualify as long-term based on duration and nature.
• Eliminate options with short-term elements like immediate repayment liabilities.
• Select the option where all components align with long-term funding criteria.

Why B is correct:

• Bonus issue of shares capitalizes reserves into permanent equity (long-term per company law), leasing of premises provides multi-year asset use (finance lease definition), and trade credit can extend beyond one year in negotiated supplier terms, all adding funds without short-term debt.

Why the others are wrong:

• A includes bank loan, often medium-term with repayment schedules under one year.
• C features bonus issue (no new cash inflow) and bank loan (variable term length).
• D mixes debenture issue and rights issue (long-term) with trade credit (typically short-term, 30-90 days).

Final answer: B
