I feel like I’ve seen RSA mentioned as an asymmetric algorithm in my notes, so I think that’s the answer here.

I’m a bit confused. I know AES and DES are symmetric, but I can't recall if RC4 is also considered symmetric or not.

I think RC4, AES, and DES are all symmetric key algorithms, but I'm not completely sure about RSA.

Wait, I'm getting a bit confused here. Aren't AES and DES both symmetric key algorithms? I better double-check my notes to make sure I'm remembering this correctly.

Hmm, I'm a bit unsure about this one. I know the differences between symmetric and asymmetric encryption, but I'll need to think through the specific algorithms to determine which one is not symmetric.

Okay, let me think this through step-by-step. RC4, AES, and DES are all symmetric key algorithms, so the one that's not symmetric must be RSA. I'm going to go with D.

Okay, I've got this. The 'featurization' parameter is the one we want to use to handle missing values and categorical features. 'auto' is the right value to automatically handle those data issues.
