Since the string of characters given is likely a hexadecimal code, we can split it into pairs to convert it to a sequence of numbers. This gives us: 
11 eb bb 8f b9 99 bd 75 bc f2 ff df 21 c5 61 07 TB8306 11

The section TB8306 seems to be an identifier and doesn't fit the pattern of the rest, so we can ignore it for now.

We want to decode the hexadecimal string to decimal, but it's unclear how many digits each pair should be. One approach is to try different possibilities and see which gives a reasonable answer. For example, if we assume that each pair should be a two-digit decimal number, we get: 
17 235 187 143 185 153 189 117 188 242 255 223 33 197 97 7

Notice that the first number is 17, which may correspond to choice D. However, if we continue to look at the rest of the values, we notice that many of them are larger than 13 in absolute value. This rules out D and suggests that each pair of characters should be interpreted as a signed byte, which gives a range of -128 to 127. Using this interpretation, we get: 
17 -21 -69 -113 -71 -103 -67 117 -68 -14 -1 -33 33 -59 97 7

Now we see that the first value is positive and between 13 and 65, which corresponds to choice C. The other values are all negative, but their absolute values are all less than 65, so they fall within the range (-65,65], which confirms choice C as the correct answer.
