• A. it has low resistivity
• B. it has high resistivity
• C. it has low melting point
• D. it remains cool for long time

Answer 1

The correct option is B

it has high resistivity

Nichrome is used for heating in most of the electrical appliances like electric iron, stove etc because, nichrome has very high resistivity, high melting point, and it remains in red hot condition for long period. So, from the given choices only one is correct which mentions about high resistivity. Remaining choices fail to explain the property of nichrome.
