D.
48

E.
128

Explanation:
Every WPA key includes a 48 bit IV key,which creates 500 trillion combinations and is a stronger
encryption compared to WEP. With so many combinations,the possibility of the encryption key
reuse is lesser and therefore the encryption can endure hacking attacks better than WEP. WPA
does not make direct use of the master encryption keys and has a message integrity checking
facility.
