The question seems to be asking which of the given options is a valid diagonalization of the matrix A, given its eigenvalues and corresponding eigenvectors.

The diagonalization of a matrix A is given by the formula A = PDP^-1, where P is the matrix whose columns are the eigenvectors of A, and D is the diagonal matrix whose entries are the eigenvalues of A.

The correct diagonalization should have the eigenvectors as columns in the matrix P (or V in this case), and the eigenvalues as the diagonal entries in the matrix D.

The eigenvalues are -5, -1, and 2, and the corresponding eigenvectors are [0,7,-6], [-1,3,-1], and [-7,6,4].

So, the correct diagonalization should be A = VDV^-1, with V = [[0,-1,-7],[7,3,6],[-6,-1,4]] and D = [[-5,0,0],[0,-1,0],[0,0,2]].

However, none of the options provided match this correct diagonalization. There seems to be a mistake in the options provided, as none of them have the correct arrangement of eigenvectors in V or the correct eigenvalues in D.

So, the answer is that none of the provided options are a valid diagonalization of the matrix A.
