I’m not sure about C, it doesn’t seem right for counting.

Definitely B, it’s the standard way to count words in Spark.

Wait, isn’t D just a typo with "flatmap"?

I think A could work too, but not as efficiently.

I feel like option C could work too, but I’m not confident about using `groupByKey` for counting words.

I practiced a similar question, and I think option B is the right choice since it correctly maps and reduces the word counts.

I'm not entirely sure, but I think option A might be incorrect because it uses `map` instead of `flatMap`.

I remember we discussed how `flatMap` is often used for word counting because it flattens the results.

Hmm, I'm not sure about this one. I'll have to think it through carefully. Maybe I can find some information about RFM in the documentation.

Okay, let me think this through step-by-step. Handlebar Templates are used for the UI, so they're likely defined in a UI-related configuration. The options mention uiProperties, Configuration Settings, and Page Settings, so I'll try to eliminate the less likely ones and go with the best fit.

I remember that if a business isn't registered for sales tax, it probably won't be charging it to customers, but I'm not entirely sure which option reflects that.

It seems to me that the accuracy of the new system is key; I just hope it can match what's currently in place at our university.

I think the best practice is to use the '--addressForce' parameter when deploying a new contract. That should help maintain the same address, right?

I think user awareness and training is the most effective method to counter phishing attacks. Educating users on how to identify and avoid phishing attempts is crucial.
