Let us consider a square matrix \( A \) of order \( n \) with eigenvalues \( a, b, c \). Then the eigenvalues of the matrix \( A^\top \) could be:
Step-by-step Solution:
The eigenvalues of a square matrix ( A ) and its transpose \( A^\top \) are identical. That is, if ( a, b, c ) are eigenvalues of ( A ), then the same values are the eigenvalues of \( A^\top \). This property holds because eigenvalues are invariant under transposition.
Correct Option: (a)
