The TB8475 in the number is an indication that this is a hexadecimal number. Converting the hexadecimal portion to decimal gives us 946,789,269, and the decimal point should be placed 11 digits to the left to account for the 11 'b' digits before it. This gives us a final value of 0.000009195 in decimal form, which corresponds to choice D. The last 11 digits of the given number (TB8475_11) represent the hexadecimal value of the number. Converting this to decimal form gives 12,257,493,781. The remaining digits (11ebb63d_1b8e_8fa7_b851_a197627a3e2b) represent the exponent, which is negative 80 when considering the decimal point to be after the first digit. Therefore, the final decimal form is 0.000009195. The answer is D.
