Show answer & explanation
Correct answer: C
Concept
An IPv4 address written in dotted-decimal notation contains four decimal octets.
Each octet represents 8 bits, so its value must be from 0 to 255, and adjacent octets are separated by dots.
Application
Check the form: the candidate must contain four decimal components separated only by dots.
Check the range: apply 0 ≤ octet ≤ 255 to every component.
For 202.50.20.148, the components are 202, 50, 20, and 148. All four are in the required range, and the separators are dots.
Cross-check and contrast
300.215.317.3 contains 300 and 317, both greater than 255.
302.215@417.5 contains the @ character and also contains values greater than 255.
202–50–20–148 uses dashes instead of dots.
Result
Therefore, the IPv4 address among the given values is 202.50.20.148.
