which two are differences between symmetric and asymmetric encryption algorithms?

For the following items, which two are differences between symmetric and asymmetric encryption
algorithms? (Choose two.)

A.
Asymmetric encryption is slower than symmetric encryption

B.
Asymmetric encryption is more suitable than symmetric encryption for real-time bulk encryption

C.
Symmetric encryption is used in digital signatures and asymmetric encryption is used in
HMACs

D.
Asymmetric encryption requires a much larger key size to achieve the same level of protection
as asymmetric encryption
