Encode the message Food is good. 2 7 Break the message into groups of two letters and use the matrix M = 1 How can the message be encoded? O A. Translate each group into a sequence of integer pairs and multiply each by M -1. OB Translate each group into a sequence of integer pairs and add each to the identity matrix. C. Translate each group into a sequence of integer pairs and multiply each by M. O D. Translate each group into a sequence of integer pairs and subtract each from the identity matrix. Encode the message. Give your answers as column matrices, where each matrix contains a pair of encoded letters. Give the matrices in the order they were encoded, which should correspond to the order of the original message. 0.0.0.0.0.0 (Type an integer or simplified fraction for each matrix element.)
