To convert from hexadecimal to decimal, we need to first convert the hexadecimal number to binary and then convert the binary to decimal. 
11eaae15_16 = 00010001111010101010111000010101_2
TB4211_11 = 1010101101000100000100010001_2
Now we need to divide the binary number by 2^32 (since there are 32 bits in a hexadecimal number) and then multiply by 100 to convert to a percentage, giving us:
00010001111010101010111000010101_2 / 2^32 * 100 = 0.12263928723%
1010101101000100000100010001_2 / 2^32 * 100 = 0.00128326583%
Adding the two percentages together gives us 0.12392255306%, which is equivalent to 0.0012392255306 in decimal form, which rounds to 0.00125. Therefore, the correct answer is C.
