The given string is in the format of a hexadecimal number. To convert it to a decimal number, we can use the following steps:

1. Separate the numbers and the letters in the string: 11 e a b 4 6 d _ 1 e 6 0 _ 1 6 3 5 _ a c d b _ 3 b 6 5 e a 6 a f 7 e d _ T B 4 2 8 1 _ 1 1

2. Convert each hexadecimal digit to its decimal equivalent:

1 1 e a b 4 6 d _ 1 e 6 0 _ 1 6 3 5 _ a c d b _ 3 b 6 5 e a 6 a f 7 e d _ T B 4 2 8 1 _ 1 1
    1 1 14 10 11 4 6 13  _ 1 14 6 0  _ 1 6 3 5 _ 10 12 13 11 _ 3 11 6 5 14 10 6 15 7 14 13 _ T B 4 2 8 1 _ 1 1
    
3. Multiply each digit by its corresponding place value (16 raised to the power of its position, starting from 0 on the right):

1*16^0 + 1*16^1 + 14*16^2 + 10*16^3 + 11*16^4 + 4*16^5 + 6*16^6 + 13*16^7  + 1*16^9 + 14*16^10 + 6*16^11 + 0*16^12 + 
    1*16^14 + 6*16^15 + 3*16^16 + 5*16^17 + 10*16^18 + 12*16^19 + 13*16^20 + 11*16^21 + 3*16^22 + 11*16^23 + 6*16^24 + 
    5*16^25 + 14*16^26 + 10*16^27 + 6*16^28 + 15*16^29 + 7*16^30 + 14*16^31 + 13*16^33 + 10*16^34 + 11*16^35 + 4*16^36 + 
    2*16^37 + 8*16^38 + 1*16^39 + 1*16^41
    
4. Add up all the products:

= 11 + 16 + 5324 + 40960 + 723401 + 270549120 + 4429185024 + 236223201792 + 
      4294967296 + 152587890625 + 3844335937500 + 0 + 165216101262848 + 1055050234506240 + 
      1829656413291520 + 9755708039400960 + 30672000000000000 + 304031844813783040 + 
      1179003804345858560 + 7456548456358159872 + 27991975521467587584 + 2061290244251072512 + 
      107839900364538916096 + 500037031693726990080 + 2422278221171793777664 + 
      22300745198530623196160 + 803469549370375588648960 + 5500363634835981072582656 + 
      61472354480983505596803072 + 2251799813685248 + 36893488147419103232 + 
      18734974482588072144896 + 18014506834207040416
    
5. Convert the resulting decimal number to its floating-point representation:

-1.04 x 10^38

Therefore, the best choice is B: -10.4.
