A factor pair are 2 numbers that multiply to get a certain product. For 200, we can make factors out of it. 1 x 200, 2 x 100, 4 x 50, 5 x 40, 8 x 25, 10 x 20. Looking at our answers, the ones that match our factors are: A.) B.) C.) However, we are looking for the pair that IS NOT a factor. But D.) does not match, so D is our answer. I hope this helps!
