I'd write a clever comment about index puns, but I'm too in-dexed right now.

F is a bit of a trick question. Of course an update can affect the indexes - that's kind of the whole point of having them!

E is also incorrect. When a table goes to the recycle bin, its indexes don't disappear forever.

B is just plain wrong. You can't access an index without accessing the underlying table.

A and D are the correct answers here. Indexes can be altered, and updates to a table can definitely affect its indexes.

I think statement D is true as well. An update to a table can result in updates to its indexes.

I agree with you, Omega. I also believe statement B is true because a SELECT statement can access indices without accessing tables.
