What does it mean to 'obliterate' something?

To 'obliterate' something means to eliminate it completely, leaving no trace behind. This term is often used in contexts where an item, memory, or idea is thoroughly erased or destroyed, indicating total removal or the act of wiping out. The concept encompasses not just making something less visible or apparent, but rather ensuring that it is entirely gone. This can apply to physical objects, like obliterating evidence, or more abstract things, like obliterating doubts or fears. The other choices do not convey this sense of total removal—examining closely implies careful scrutiny, modifying slightly indicates minor changes, and enhancing selectively suggests improvement rather than destruction.
