Correct answer: A

Explanation

Converting each 8-bit binary octet to decimal yields the correct IPv4 address. Specifically, 10101100 converts to 172, 01111011 converts to 123, 00001101 converts to 13, and 10011101 converts to 157. Therefore, 172.123.13.157 is the correct representation, while the other options contain incorrect decimal conversions for one or more octets.
