B. $444.44  

Step-by-step explanation:

We have been given that Andrew buys a home entertainment system from an electronics store offering 0% interest for 18 months. This means if she pays monthly payment she will not be charged with any interest for 18 months.

Therefore, Andrew should make a monthly payment of $444.44 to avoid paying deferred interest charges for the $8,000 system. and option B is the correct choice.
