Correct Answer:
D. Wisdom
The word Sagacity refers to the quality of having or showing keen mental discernment and good judgment; shrewdness. Therefore, its closest synonym is Wisdom, which is the quality of having experience, knowledge, and good judgment.
- Morality refers to principles concerning the distinction between right and wrong or good and bad behavior, which is different from intellectual judgment.
- Uprightness means honesty and respectability, a moral quality rather than an intellectual one.
- Stupidity is the quality of being unintelligent or foolish, which is an antonym of sagacity.
Thus, 'wisdom' accurately captures the essence of profound understanding and good judgment inherent in 'sagacity'.
