Explanation:

Option 3 :

Payment to Trade Payables will improve the Current Ratio

Bill payable will decrease both current assets(cash) and current liabilities (bill payables) . Hence current ratio will increase.

 Lets assume

CA = 20,000 , CL= 10,000 payment 2,000 is made against bills payable

CR= (20,000-2,000)/(10,000-2,000) = 18,000/8,000 = 2.25 : 1

Option 1 : will increase cash & decrease bils receivable so no impact

Option 2 :  Will incerase stock & decrease cash no impact

Option 4 : Will incease stock & creditors hence decesase ratio
