Option c would be the correct answer. The size of the convoluted matrix is given by C = ((I-F+2P)/S)+1, where C is the size of the convoluted matrix. I is the size of the input matrix. F is the size of the filter matrix. P is the padding applied to the input matrix. S is the stride applied. Here I = 12, F = 3, P = 0, S = 1 Therefore the answer is 10 X 10 matrix.
