    Feel free to ask if you have any doubt.

    eduncle-logo-app

    option d aslo has 4 as a eigen value

    eduncle-logo-app

    option b aslo has 4

    eduncle-logo-app

    See I have discarded option b,d based on trace value

    eduncle-logo-app

    I have also written that option c only satisfies the value of trace.

    eduncle-logo-app

    Any doubt?

    eduncle-logo-app

    but how did you discard b & d

    eduncle-logo-app

    On the basis of "Sum of Eigen value = Trace of matrix", As trace is " -4 " then sum of Eigen values should be"-4".

    eduncle-logo-app

    Eigen values in Option B and D , Their sum is not "-4".

    eduncle-logo-app

    Do you get it ?

    eduncle-logo-app

    yes

    eduncle-logo-app

    okay
