We can add the hexadecimal numbers digit by digit using the sum formula.
1+1 = 2
e+b = 19
a+1 = b
9+1 = a
8+4 = c
4+9 = d
e+2 = 10
a+9 = 13
f+9 = 1e
7+5 = c
3+8 = b
4+0 = 4
0+5 = 5
1+1 = 2

The result is 219bca10aecd452c05 which is a hexadecimal number. To convert it to decimal, we can use the calculator or the conversion formula. The value of the hexadecimal number is 73022196626461570084109317 in decimal.

Next, we can add the digits in the decimal number:
7+3+0+2+2+1+9+6+6+2+6+4+6+1+5+7+0+0+8+4+1+0+9+3+1+7 = 99

Therefore, the answer is C (360).
