Select the pair that best expresses a relationship similar to that expressed in the original pair:
OATH : ALLEGIANCE
Correct: D
An OATH is a formal promise or declaration, typically made in solemn assertion of truth or in witness of a pledge, and is often taken to confirm ALLEGIANCE. The relationship is 'a formal declaration used to affirm or express a commitment'. Similarly, a PLEDGE is a solemn promise or undertaking, often given to express LOYALTY. While a vow is part of marriage, and signature part of a document, pledge:loyalty captures the solemn commitment/declaration relationship most accurately.
