please please help with all! i will upvote pleaseee i am stuck

Let A and E be matrices with the following sizes. A: 2 x 3 E: 3 x 2 If defined, determine the size of the matrix E - 24. (If an answer is undefined, enter UNDEFINED.) If not defined, explain why. O E - 2A is defined. O E - 2A is not defined because E and 2A have different sizes. O E - 2A is not defined because E and 2A have the same size. O E - 2A is not defined because the number of columns of E does not equal the number of rows of 24. O E - 2A is not defined because the number of rows of E does not equal the number of columns of 24.
