The combination behaves as a single wire then its Young's modulus is :AY=2Y1Y23(Y1+Y2)Y = {{2{Y_1}{Y_2}} \over {3({Y_1} + {Y_2})}}Y=3(Y1+Y2)2Y1Y2BY=2Y1Y2Y1+Y2Y = {{2{Y_1}{Y_2}} \over {{Y_1} + {Y_2}}}Y=Y1+Y22Y1Y2CY=Y1Y22(Y1+Y2)Y = {{{Y_1}{Y_2}} \over {2({Y_1} + {Y_2})}}Y=2(Y1+Y2)Y1Y2DY=Y1Y2Y1+Y2Y = {{{Y_1}{Y_2}} \over {{Y_1} + {Y_2}}}Y=Y1+Y2Y1Y2Check answerSkip
