2Compute each matrix sum or product if it is defined. If an expression is undefined, explain why. Let A =4- 372C =2 3- 5B =- 53- 3- 4-3 23 5- 6D=and E =-2 34 Compute the matrix product EB. Select the correct choice below and, if necessary, fill in the answer box within your choice.O A. EB =(Simplify your answer.)B. The expression EB is undefined because the number of columns in E is not equal to the number of columns in B.C. The expression EB is undefined because the number of columns in E is not equal to the number of rows in B.D. The expression EB is undefined because the number of rows in E is not equal to the number of columns in B.
