The correct answer is A. 11110111101.
A hexadecimal number is a number that uses the digits 0-9 and the letters A-F to represent values. The binary equivalent of a hexadecimal number is the number that is represented by the same digits in binary. To convert a hexadecimal number to binary, you can use the following table:
Hexadecimal | Binary
——- | ——–
0 | 0000
1 | 0001
2 | 0010
3 | 0011
4 | 0100
5 | 0101
6 | 0110
7 | 0111
8 | 1000
9 | 1001
A | 1010
B | 1011
C | 1100
D | 1101
E | 1110
F | 1111
To convert the hexadecimal number 7BD to binary, you would first write down the digits of the number, starting with the rightmost digit and working your way to the left. Then, you would look up each digit in the table and write down the corresponding binary digit. For example, the rightmost digit of 7BD is D, which corresponds to the binary digit 1101. The next digit is B, which corresponds to the binary digit 1011. The next digit is 7, which corresponds to the binary digit 0111. And the last digit is A, which corresponds to the binary digit 1010. So, the binary equivalent of 7BD is 11110111101.
Option B is incorrect because it is not a binary number. Option C is incorrect because it is not a binary number. Option D is incorrect because it is not a valid answer. Option E is incorrect because it is not a valid answer.
