    \[3x-2y=\mu \]                            
    Which of the following statement(s) is (are) correct?

    A)  If \[a\ne -\,3,\] then the system has a unique solution for all values of \[\lambda \] and \[\mu \]

    B)  If \[\lambda +\mu =0\], then the system has infinitely many solutions for \[a=-\,3\]

    C)  If \[\lambda +\mu \ne 0,\] then the system has no solution for \[a=-\,3\]
