The question is asking us to determine the net profit of a company in 1991 given its total revenue, total cost, and tax paid. The company earned a total revenue of =₦=108 million and had a total cost of =₦=91 million. To calculate the gross profit, we need to subtract the total cost from the total revenue:

Gross Profit = Total Revenue - Total Cost = =₦=108 million - =₦=91 million = =₦=17 million

We are also told that the company paid a tax of =₦=4596 on its gross profit. To calculate the net profit, we need to subtract the tax paid from the gross profit:

Net Profit = Gross Profit - Tax Paid = =₦=17 million - =₦=4596 = =₦=9.35 million

Therefore, the correct answer is Option C: =₦=9.35 million. It is important to note that net profit is the amount of money a company makes after deducting all costs and expenses, including taxes, from its total revenue.
