Since the problem involves hexadecimal addition, we need to convert all the hexadecimal digits to decimal before performing the addition. 
11ebb7d6 = 4,295,798,934 
6ebc_bfbf = 184,483,860,479 
ad4c_71b1_8326_c6ff = 308,647,055,421,735

TB8285 = 11,331,077

Performing the addition: 
4,295,798,934 + 184,483,860,479 + 308,647,055,421,735 + 11,331,077 = 308,835,589,102,225

Now we convert the sum to hexadecimal: 
308,835,589,102,225 in hexadecimal is d6e07e1cbf1, so choosing D is the correct answer.
