D seems like a copy of C, but with the same mistakes.

Wait, why are there two different spellings of "female"?

C has some syntax issues, not sure it’ll work.

I feel like we had a similar question on the last practice exam, and I think the correct approach was to use the filter method effectively, like in option C.

I'm a bit confused about the difference between options B and D. They seem really similar, but I can't recall which one is actually correct.

I think option C looks familiar; it uses RDDs and seems to follow the logic we discussed in class about aggregating data.

I remember we practiced filtering data based on conditions, but I'm not sure if the syntax for the SQL query is correct in option A.

Okay, let me think this through. I know we need to do something with the multilist field, but I'm not sure if that's the only step.

I'm a bit unsure about this one. The wording of the question and answer choices is a little confusing. I'll need to re-read it a few times to make sure I fully understand the concept before selecting an answer.

I feel like "All of the above" is a trick option here.Only one component is executing the processes, but I can't recall which one for sure.

Hmm, I'm a bit unsure about this one. I know enterprise networking involves things like LANs and WANs, but I'm not sure if that's the full answer. I'll have to think this through carefully.

Okay, let me break this down. The Act is meant to provide transparency in public authorities, so I'm guessing it wouldn't cover the high courts or state legislatures since they have their own processes. I'll go with B for now, but I'm not 100% sure.

Option B gets my vote. It's like the 'Goldilocks' of the options - not too complex, not too simple, just right!

I'm a bit confused by the syntax in option C and D. The code seems a bit verbose and convoluted compared to option B, which is more readable and easier to understand.
