Which of the following best describes estimable?

The term "estimable" means deserving of respect or high regard. It originates from the verb "esteem," which signifies holding someone or something in high evaluation or admiration. When something or someone is described as estimable, it implies that they possess qualities that are admirable or worthwhile, prompting others to regard them positively. This can apply to various contexts, such as personal attributes, achievements, or even contributions to a field or society.

The other options do not align with this definition, as they either denote a lack of value, merit, or respect. Thus, "deserving of respect or high regard" accurately captures the essence and appropriate usage of "estimable."
