Problem #2: Let R^4 have the Euclidean inner product, and let W be the subspace spanned by the vectorsU1 = (1,0,1,0), U2 = (0,-1,1,0), and U3 = (0,0,1,-1).Use the Gram-Schmidt process to transform the basis U1, U2, U3 into an orthonormal basis.(A) v1 = (1,0,0,0), v2 = (-4,1,1,0), v3 = (1,4,0,1)(B) v1 = (1,0,0,0), v2 = (0,5,0,0), v3 = (1,-1,0,0)(C) v1 = (-1,0,0,0), v2 = (0,1,0,0), v3 = (1,1,0,0)(D) v1 = (1,0,0,0), v2 = (-1,1,1,1), v3 = (1,1,1,1)(E) v1 = (1,0,0,0), v2 = (0,4,0,0), v3 = (1,1,0,-4)(
