Question

Select the most appropriate synonym of the given word:

PERFIDIOUS

1. A. Honest
2. B. Faithful
3. C. Treacherous (Correct answer)
4. D. Loyal

Correct Answer

Option C — Treacherous

Detailed Solution & Explanation

The correct answer is Treacherous.

Key Points

• 'Perfidious' means guilty of betrayal — deceitful, faithless, untrustworthy.
• Its closest synonym is Treacherous.
• Honest, faithful and loyal are all antonyms, so they cluster on the opposite side; the one 'betrayal' word is the synonym.
• Recognising that three options mean the reverse is often faster than defining the headword cold.
