Edited. I'll clean up points in the am.
Sorry, but option 1 is still wrong.
Exclusive locks prevent access to a resource by concurrent transactions
Read access is not prevented in case of NOLOCK or READ UNCOMMITTED
So either this option needs to be removed from the correct options, or it needs to be reworded to show that write access to a resource is prevented and not read access.
