Choose the correct answer below.
A. Vector b is a linear combination of a,, a,, and az. The pivots in the corresponding echelon matrix are in the first entry in the first column, the second entry in the
second column, and the third entry in the third column.
B. Vector b is a linear combination of a,, a,, and az. The pivots in the corresponding echelon matrix are in the first entry in the first column, the second entry in the
second column, and the third entry in the fourth column.
O C. Vector b is not a linear combination of a,, a2, and a3.
D. Vector b is a linear combination of a,, a,, and az. The pivots in the corresponding echelon matrix are in the first entry in the first column and the second entry in
the second column.
