Hint: In series combination the appliances are connected in end-to-end arrangements while in the parallel connection each component of the circuit is connected separately to the supply. In series combination current is passing through each component to complete the circuit while for the parallel combination the current will flow through each component separately.

Complete step-by-step answer:
 In domestic circuits the arrangement that is used is parallel connection of the components. The reason behind using the parallel arrangement in the domestic circuits are as follows-
i.In parallel, if one appliance stops working due to some fault then the working remaining appliances in the house will not be interrupted. While in the series combination if one appliance will stop to work then circuit will not be completed and all the appliances will be stopped.
ii. In the parallel combination there are separate switches for each and every appliance, we can switch then ON or OF separately, without interrupting the working of the other appliances.
iii. In the parallel connection the overall resistance is lower in comparison of the series connection, this gives the high current from the power supply.
iv. Each appliance will get the same voltage as that of the voltage of the power supply line in the parallel connection.
So, from the above discussion we came to the conclusion that the arrangement of the domestic circuit is parallel,

So, the correct answer is “Option B”.

Note: Though the parallel connection has many advantages over series connection but there are some disadvantages related to the parallel connections. Those are like the parallel connection will require more wires than the series, we will not be able to decrease or multiply the voltage in the parallel circuit, and if we have to pass the same amount of the current through all the appliances then the parallel connection will not be helpful.
