Fill in the blank.
He bids fair to set his enemy ________.

Correct option is B

Correct option: (b) down
Meaning of the phrase (bids fair to):
• Bids fair to → seems likely to; shows probability (Hindi: संभावना है कि)
Meaning of the phrasal verb (set down):
• Set down (someone) → to put down / belittle / humiliate / criticize harshly (Hindi: नीचा दिखाना / अपमानित करना)
• Why it fits: “enemy” suggests an action of defeating/putting down.
Correct sentence: He bids fair to set his enemy down.
Grammatical Rule (English):
• Phrasal verbs take fixed particles; changing the particle changes the meaning.
व्याकरणिक नियम (Hindi):
• Phrasal verb में particle तय होता है; particle बदलने पर अर्थ बदल जाता है। “set down” का अर्थ नीचा दिखाना है।
Meanings of other options (in detail):
• (a) set out → begin/start; start a journey or task (Hindi: आरम्भ करना / रवाना होना)
• (c) set off → start a journey; trigger/activate (Hindi: रवाना होना / शुरू करना)
• (d) set away → standard usage इस अर्थ में नहीं; गलत संदर्भ (Hindi: प्रचलित नहीं)
Hence, option (b) is the correct answer.
