1. Multiply the non-zero digits of both numbers: 
   116e x b5cb = 52684f6c
2. Count the number of zeros in both numbers:
   TB8285 has 6 zeros and 11ebb7d6_6eae_b5cb_ad4c_2b0f550b83dd has 10 zeros.
3. Add the number of zeros from both numbers (6+10 = 16).
4. Place the 16 zeros to the right of the result found in step 1:
   52684f6c0000000000
5. Convert the result back to hexadecimal:
   52684f6c0000000000 = 11ebb7d6000000016eae_b5cb_ad4c_2b0f550b83dd
6. Round down the result to the nearest hundred, which gives us 1,380,000. 
Therefore, the answer is B) 1,380,000.
