The eigenvector(s) is/are (Use a comma to separate vectors as needed.) Find a basis of each eigenspace of dimension 2 or larger. Select the correct choice below and, if necessary, fill in the answer boxes to complete your choice. OA. Exactly one of the eigenspaces has dimension 2 or larger. The eigenspace associated with the eigenvalue À= has basis (Use a comma to separate vectors as needed) OB. Exactly two of the eigenspaces have dimension 2 or larger The eigenspace associated with the smaller eigenvalue λ = has basis and the eigenspace associated with the larger eigenvalue = has basis (Use a comma to separate vectors as needed.) OC. None of the eigenspaces have dimension 2 or larger
