As a decimal number.
As an octal number.
As a hexadecimal number.
As a binary number.

The correct answer is: As a hexadecimal number.

Option A is incorrect because decimal numbers use a base 10 number system. Option B is incorrect because octal numbers use a base 8 number system. Option D is incorrect because binary numbers use a base 2 number system.
