Answer: A
Appliances are connected in parallel because it makes the operation of appliances independent of each other.
In a parallel circuit every appliance is connected directly across the supply and gets the full supply voltage it is rated for. Each one can be switched on or off without affecting the others, and if one fails the rest keep working. In a series circuit one switch or one failure would cut off everything, and the voltage would be shared out between the appliances.
A parallel circuit actually draws more total current, since the branch currents add, and it does not reduce power loss. It is the independence of the appliances, not simplicity, that decides the choice.
