Since Erika spent a total of 11ebb63d_1c18_f517_b851_038693d566f4_TB8475_11 hr visiting both websites and spent 11ebb63d_1c19_1c28_b851_23291b5c4a95_TB8475_11 hr at the history channel website, we can subtract the two to find how many hours were spent at the discovery channel website:
11ebb63d_1c18_f517_b851_038693d566f4_TB8475_11 - 11ebb63d_1c19_1c28_b851_23291b5c4a95_TB8475_11 = 11ebb63d_1c19_1c2b_b851_3be60a22e4da_TB8475_11
Therefore, the answer is C. Erika spent a total of 11ebb63d_1c18_f517_b851_038693d566f4_TB8475_11 hours on both websites, and spent 11ebb63d_1c19_1c28_b851_23291b5c4a95_TB8475_11 hours on the history channel website. 
To find how long she spent on the discovery channel website, we can subtract the time she spent on the history channel website from the total time:
11ebb63d_1c18_f517_b851_038693d566f4_TB8475_11 - 11ebb63d_1c19_1c28_b851_23291b5c4a95_TB8475_11 = 
11ebb63d_1c19_1c2b_b851_3be60a22e4da_TB8475_11
