-(x-z): odd - even = odd -y²: odd × odd = odd -(x-z)²: odd × odd = odd -(x-y): odd - odd = even *এখন options গুলি যাচাই করি: -(A) সত্য: odd × odd = odd -(B) সত্য নয়: odd × odd = odd (even নয়) -(C) সত্য: odd × odd = odd -(D) সত্য: even × even = even *সুতরাং, (B) (x-z)²y is even হল একমাত্র statement যা true হতে পারে না। এটি সবসময় odd হবে। *তাই সঠিক উত্তর হল (B) (x-z)²y is even।Related questions
