Hi, Here is the question

9. Which statement is true?
A. Classes loaded into a browser from the local network are trusted.
B. Classes loaded into a browser from remote sources are trusted if they are signed.
C. Classes loaded into a browser from remote sources are trusted if they are in a signed jarfile.
D. Classes loaded from a jarfile on a remote source can sometimes be trusted even if the jarfile is unsigned.
E. Classes loaded from a signed jarfile are trusted if the public key associated with the jarfile's signature is
marked as trusted in the keystore.

Regards
