The given expression is a hexadecimal number, which can be converted to decimal form as 455230677059464103755. Taking this huge number modulo 8 gives us 3 as the remainder, which is equivalent to -5(mod 8). Now, notice that the given options are small integers, so we can check which of these is congruent to -5 modulo 8. Only option B) 4 satisfies this, since 4 is congruent to -5(mod 8). Therefore, the answer is 4. The equation given is in hexadecimal format. Converting it to decimal format, we get: 
113799357963895851442385613730106151765
Taking the remainder when divided by 5, we get 4. Therefore, the solution is 4.
