The correct answer is A. 6316.
To convert a binary number to hexadecimal, you can use the following steps:
- Divide the binary number by 16, and write down the remainder.
- Continue dividing the quotient by 16, and writing down the remainders.
- Starting from the bottom, write down the remainders in reverse order.
In this case, the binary number is 11000112. Dividing by 16 gives a quotient of 70 with a remainder of 12. Dividing 70 by 16 gives a quotient of 4 with a remainder of 10. Dividing 4 by 16 gives a quotient of 0 with a remainder of 4. The remainders in reverse order are 4, 10, 12, and 70. This is equivalent to the hexadecimal number 6316.
Option B is incorrect because 5716 is not equivalent to 11000112 in binary. Option C is incorrect because 4616 is not equivalent to 11000112 in binary. Option D is incorrect because 4016 is not equivalent to 11000112 in binary. Option E is incorrect because the answer is not none of the above.
