What condition should hold in order to multiply two matrices?

Option A is correct

In order to multiply two matrices the number of columns of the first matrix should be equal to the rows of the second matrix. The output matrix will have rows equal to the rows of first matrix and coloumns equal to the number of columns of second matrix.

Option B is incorrect because here the number of rows and coulumns are interchanged for matrix one and two respectively.

Option D is incorrect because two matrices having the same size can be multiplied but it is not a necessity.

Matlab Queatoin: The test suite generates a random M x N matrix with a random number of rows and columns that is assigned to the variable A . The element values of the matrix are random double precision numbers that fall in the range from -10 to 10. The matrix has between 5 and 10 rows and between 5 and 10 columns. Assuming A is defined in the workspace, write a script with commands to perform the operations described below...

Hi, I know that if two matrices A and B are similar matrices then they must have the same eigenvalues with the same geometric and algebraic multiplicities. However, I was wondering if that statement was equivalent. In order terms, if two matrices have the same eigenvalues with the same algebraic multiplicities, must they be similar? What about geometric multiplicities?
