A is the way to go. I mean, 50 executors with 20GB each sounds like a party, but option B just sounds like a recipe for a memory management disaster.

Haha, imagine trying to run a Spark app with 80 executors, each with 40GB of memory. That's like trying to fit an elephant in a shoebox!

I think B is better because more memory and executors will improve performance.

Option B doesn't seem right. Requesting 40GB of memory per executor and 80 executors is overkill for the given requirements.

I think the correct answer is A. The question specifically asks to set the executor memory to 20GB and the number of executors to 50, which matches the values in option A.
