Step 1: Method:
Ask what the money is for. Money from day-to-day business is operating. Money from buying or selling long-term assets or earning from them is investing. Money from owners or lenders is financing. Money held in hand or as near-cash is cash equivalent.
Step 2: Apply to A and B:
Royalty, fee and commission come from selling services in the normal course of business, so A is operating (II). Interest and dividend come from money placed in investments, so B is investing (I).
Step 3: Apply to C and D:
Issuing shares brings in capital from owners, so C is financing (IV). A current investment can be encashed quickly with little risk, so D is a cash equivalent (III).
Step 4: Match with the options:
The sequence II, I, IV, III is given only in option 3. The other three options each put A under I or III, which does not fit an operating income.
Final Answer:
Option 3 is correct. \[\boxed{\text{A-II, B-I, C-IV, D-III}}\]
