    Resistivity is costant and resistance increase 4 time to the original resistance because if the wire is stretched than length is double and area of cross section ki half

    Risistivity is constant for any material at a particular temperature so there will be no change in resistivity, however the resistance will change and according to the question it will be 8 times the preVious resistance.
