To find the matrix sum, we add the corresponding elements of each matrix. In this case, we can see that the first three groups of digits in all three matrices are the same, so we can ignore them. Adding the fourth group of digits for each matrix gives us: 2ada + 2adb = 51ec. Solving for the missing digit in the sum, we get 51ec - 2ada = a00e. Therefore, the correct matrix sum is 11ea984b_ae88_a00e_9029_3b35f1723339_TB4005_11, which corresponds to choice C.
