ECDHE_ECDSA vs RSA

[Trevor Chandler]

Okay, here's my second question in this latest series:

Question: Why is using ECDHE_ECDSA stronger than using RSA?

A. ECDHE_ECDSA provides both data authenticity and confidentiality.

B. ECDHE_ECDSA uses a pseudorandom function to generate the
keying materials.

C. If the server's private key is later compromised, all the prior TLS
handshakes that are done using the cipher suite cannot be
compromised.

D. ____________________________________________________________________


Your answer goes here:


Note: I'll remove some of the pressure to provide a correct response
by removing any penalty of detention!!!

Really? None of the Answers really fit to the Question.
A: Let`s hope RSA also provides authenticity and confidentiality
B: wrong
c: its called PFS, which is part of DH
d: ???? nothing there.
e: Comparatively new public-key cryptography method compared to RSA, standardized in 2005.
(RSA from 1995)
