To "expunge" something means to:

The term "expunge" specifically refers to the act of removing or erasing something completely. It is often used in legal contexts where a record is destroyed or erased to eliminate any trace of it. The core meaning centers on deletion or obliteration, thus, the correct understanding aligns perfectly with the idea of removing something by erasing or crossing it out.

In contrast, the other options suggest actions that increase presence or accessibility, such as increasing visibility, enhancing features, or duplicating, none of which captures the essence of removal implied by "expunge." Understanding the specific context in which "expunge" is typically used can further reinforce the accuracy of the chosen answer.
