    A)  \[8.3\,\,cm,\,\,3.4\,\,cm,\,\,6.1\,\,cm\]

    B)         \[5.4\,\,cm,\,\,2.3\,\,cm,\,\,3.1\,\,cm\]

    C)         \[6\,\,cm,\,\,7\,\,cm,\,\,10\,\,cm\]

    D)         \[3\,\,cm,\,\,5\,\,cm,\,\,5\,\,cm\]

    Correct Answer: B

    Solution :

    For any triangle sum of any two sides is greater than the third side. But in option B, \[2.3+3.1>/5.4\] Hence, it is not possible to construct a triangle.
