The given solution contains two different variables represented by the hex values after the underscores. The variables have the same prefix (11ea71d0_de4f_91e5_TB6077_11), but different suffixes. The equation given can be written as:
(11ea71d0_de4f_a8af_91e5_41b8a5cf94dd_TB6077_11) + (11ea71d0_de4f_a8b0_91e5_e1d2d59d365e_TB6077_11) = (1 × 11ea71d0_de4f_a8b1_91e5_6fe48da77371_TB6077_11) M
To simplify, let's focus only on the suffixes and rewrite the equation as:
x + y = zM
where x = 41b8a5cf94dd, y = e1d2d59d365e, and z = 6fe48da77371. We want to find the value of z plus one in the same format (11ea71d0_de4f_cfc4_91e5_TB6077_11), which means we need to add 1 to the suffix of z and convert to hex. 
z + 1 = 6fe48da77372
The closest option to this is C, which has a suffix of 6b8de274f4bc.
