Question

Select the option that best completes the sentence: "Had I known about the meeting earlier, I ____ attended it."

• A. would have
• B. will have
• C. had
• D. would be

Hint:

Type-3 conditionals describe imaginary situations in the past. They follow the pattern: "If + past perfect, then + would have + V3."

Answer 1

The Correct Option is A

Step 1: Identify the sentence type. 
This is a Type-3 conditional sentence (unreal past condition) used to express regret or hypothetical situations in the past. 
Step 2: Applying the correct structure. 
The correct structure is: 
"If + past perfect, then + would have + past participle." 
Here, "Had I known" is the inverted form of "If I had known", so the second clause should be: 
"I would have attended it."
