I feel like option D is definitely optimized since it includes the IsDeleted check, but I'm unsure about the others.

I practiced a similar question where filtering out null values was emphasized, but I can't recall if that was a good strategy for large volumes.

I remember we discussed how using "IsDeleted = false" can help filter out soft-deleted records, which is important for large datasets.

The fourth option with the IsDeleted check is interesting. Filtering out deleted records could help optimize the query.

Querying the ID field directly, like in the third option, is usually a good strategy for large data volumes. I'd consider that one.

The second option with the customer number filter seems promising, since it's using an external ID field. That could help with performance.

Hmm, the first option with the NULL check seems like it could be inefficient for a large dataset. I'd want to look into that more.
