B. use of fuse
C. use of stabilizers
D. use of electric meter

Answer

B

Explanation

The most important saftey method used for protecting home appliances from short circuting or overloading is the electric fuse. This is a safety device thin wire of short length made of thin `(25%)` alloy having low melting point around `200^(@)C`.
The fuse wire is of chosen thickness, so as to fix its resistance and hence amount of heating on passage of a particular amount of current. whenever currect through the fuse exceeds the set limit, the fuse wire metls and breaks the circuit . This saves the man cicuit components from demage.
