The word "reckless" in the sentence "His reckless remark did not go unnoticed" suggests that the remark was made without careful thought or consideration of the potential consequences. Let's explore the meaning and implications of each option:

• Salient: This word means something that is most noticeable or important. It does not fit well with "reckless," as "salient" emphasizes visibility or prominence, rather than carelessness.
• Considerable: This refers to something that is significant or worthy of attention, often due to its size or importance. It does not match "reckless," because "considerable" does not imply a lack of caution or foresight.
• Taciturn: This describes a person who is reserved or says little. It is almost the opposite of making a "reckless" remark since taciturn people are cautious about speaking.
• Unguarded: This means lacking in caution or care, especially in speech or behavior. It aligns with "reckless" because both suggest speaking without careful thought or control, leading to unintended consequences.

Therefore, the option closest in meaning to "reckless" is unguarded.
