What term is used for someone who shows great attention to detail?

The term that best describes someone who shows great attention to detail is meticulous. A meticulous person is characterized by a careful and precise approach to their work, ensuring that every element is thoroughly examined and executed with a high level of accuracy. This quality often leads to high-quality results because attention to detail can prevent errors and improve the overall outcome of tasks.

In contrast, the other terms do not convey the same level of care or detail orientation. Plausible suggests something that is reasonable or believable, but does not relate to attention to detail. Reticent refers to someone who is reserved or reluctant to speak, which is unrelated to any detailed focus. Indifferent describes a lack of interest or concern, which starkly contrasts with the attentiveness implied by being meticulous. Thus, the choice of meticulous directly aligns with the notion of being thorough and detail-oriented.
