The developer must have been high on caffeine when they wrote this code. Ignore columns? What is this, a selective memory test?

This code is more complex than my grocery list. I'm just going to go with option C and call it a day.

Wait, why would you ignore columns? That's like throwing away perfectly good data! I hope the developers have a good reason for that.

I agree with Renea. Option D is wrong, the composite index 'name_index' is defined as unique.

The code seems straightforward, but option D is incorrect. The index value of the composite index 'name_index' is set to unique, so it should be correct.
