Explanation
WEP (Wired Equivalent Privacy) uses the RC4 (Rivest Cipher 4) stream cipher as its core data encryption algorithm, making option A correct. AES (Advanced Encryption Standard) is incorrect because it is a block cipher adopted by WPA2, which was designed to replace WEP precisely because of WEP's weaknesses. CCMP (Counter Mode with CBC-MAC Protocol) is also a WPA2 mechanism built on top of AES, so it belongs to a later, stronger standard. Asymmetric encryption is incorrect because WEP relies on a shared symmetric key, not a public/private key pair system typical of asymmetric schemes.
Memory tip: Think "WEP is Really old, so it uses RC4" -- the two share the letter R as a reminder. Anything stronger (AES, CCMP) belongs to the WPA2 era that came after WEP was found to be broken.
