2 Let n be an odd number 27. Let A=a, be an nxn matrix with a,in =1 for all i =1, 2,.. n -1 and a,1 =1. Let a, = 0 for all other pairs (i, j) . Then we can conclude that (a) A has 1 as an eigenvalue (b) A has -1 as an eigenvalue (c) A has at least one eigenvalues with multiplicity 2 2 (d A has no real eigenvalues
