Let A be an nxn matrix. Determine whether the statement below is true or false. Justify the answer. The determinant of a triangular matrix is the sum of the entries on the main diagonal. Choose the correct answer below. O A. The statement is true. Cofactor expansion along the row (or column) with the most zeros of a triangular matrix produces a determinant equal to the sum of the entries along the main diagonal. O B. The statement is true. The determinant of A is the following finite series. det A = E(-1)' *laydet Aj j= 1 In a triangular matrix, this series simplifies to the sum of the entries along the main diagonal. O c. The statement is false. The determinant of a triangular matrix is the product of the entries along the main diagonal. O D. The statement is false. The determinant of a matrix is the arithmetic mean of the entries along the main diagonal.
