Answer 1

Hint: To answer this question first we have to understand the meaning of Equipment earthing and neutral point earthing. Then we will easily choose from these options.

Complete Step-by-Step solution:
So first we have to understand equipment earthing and neutral point earthing.
Equipment earthing: As we can understand from the equipment that we have earth the equipment to save the equipment from short circuit and high voltage current. In this type of earthing a wire is connected through equipment to main earthing which is connected to earth directly.
Neutral point earthing:
Neutral point earthing is for earth grounded systems in which the system is directly connected to earth for any fault and for high voltages, when high voltages come then it transfers to earth and saves the system.
Hence option B is the correct option. Because equipment earthing is provided for safety of electrical appliances.

Note: Whenever we get this type of question the key concept of solving is we have to understand all the terms used in question then we will be able to answer this type of questions very easily. For better understanding we should see real life examples.
