The correct answer is B. Reduce.
When a company pays an expense, it reduces its assets. This is because the company is no longer able to use the cash or other assets that it used to pay the expense.
Option A is incorrect because payment of expenses does not increase assets. In fact, it does the opposite.
Option C is incorrect because payment of expenses does not apportion assets. Apportionment is the process of allocating costs to different parts of a business.
Option D is incorrect because payment of expenses does not overstate assets. Overstating assets is when a company reports its assets as being worth more than they actually are.
I hope this helps!
