This appears to be a complex equation, but it is actually in the format of a standard deviation calculation using the formula σ = √(Σ(xi - x̄)²/N). 
To solve, we need to convert the alphanumeric values into numerical values. 
11 = 1
ea = 234
b4 = 180
6d = 109
1e = 30
60 = 96
b2 = 178
83 = 131
ac = 172
db = 219
21 = 33
8f = 143
47 = 71
e9 = 233
47 = 71
33 = 51
TB4281 = (234 + 180 + 178 + 131 + 172 + 219 + 233) / 7 = 166.14
Using these numerical values, we can simplify the equation:
√((1-166.14)² + (234-166.14)² + (180-166.14)² + (109-166.14)² + (30-166.14)² + (96-166.14)² + (178-166.14)² + (131-166.14)² + (172-166.14)² + (219-166.14)² + (33-166.14)² + (143-166.14)² + (71-166.14)² + (233-166.14)² + (71-166.14)² + (51-166.14)²)/16
Simplifying further, we get:
√((-165.14)² + (67.86)² + (13.86)² + (-57.14)² + (-136.14)² + (-70.14)² + (11.86)² + (-35.14)² + (5.86)² + (52.86)² + (-133.14)² + (22.86)² + (95.86)² + (66.86)² + (95.86)² + (115.86)²)/16
= √(127887.84/16)
= √7992.99
= 89.38
So, the answer is (C) 0.0867
