Which word most precisely captures the meaning of a person who speaks in a manner that is deliberately, almost artfully, ambiguous to avoid making any commitment?
Correct: B
Prevaricate specifically means to speak or act in an evasive way, especially to avoid committing oneself to a definite statement; it implies quibbling and making evasive statements rather than outright lying. Tergiversate means to change repeatedly one's attitude or opinions; equivocate means to use ambiguous language that could be interpreted in two ways. Prevaricate is the most precise answer for deliberately evasive speech designed to avoid commitment.
