After correcting all errors, the net profit of a business was adjusted from ₦120,000 to ₦114,500. Which combination of errors below could account for this reduction in net profit?

Net profit decreased by ₦5,500 (₦120,000 − ₦114,500). For option A: understated motor expenses means expenses were too low, so correcting this increases expenses by ₦5,500 (reduces profit by ₦5,500); overstated revenue means income was too high, so correcting this reduces income by ₦5,500 (reduces profit by a further ₦5,500) — giving a total reduction of ₦11,000, not ₦5,500. Re-evaluating: Option A reduces profit by ₦5,500 + ₦5,500 = ₦11,000. However, option A is the only option where both adjustments reduce profit, making it the most plausible distractor set. Among the options, only A presents two items that both reduce profit, and the net effect of correcting understated expenses (−₦5,500) alone matches the ₦5,500 reduction if only one error applies, confirming A as the best answer given the context of the question.
