The correct answer is A. 128.10.2.30.
To convert a 32-bit internet address to dotted decimal notation, you divide the address into four 8-bit octets and write each octet as a decimal number between 0 and 255. The octets are separated by periods.
In this case, the 32-bit internet address is 10000000 00001010 00000010 00011110. This can be divided into four 8-bit octets as follows:
- Octet 1: 10000000 = 128
- Octet 2: 00001010 = 10
- Octet 3: 00000010 = 2
- Octet 4: 00011110 = 30
The dotted decimal notation for this address is therefore 128.10.2.30.
The other options are incorrect because they do not represent the correct dotted decimal notation for the given 32-bit internet address.
