Choose the correct phrase from the given option and make a conditional sentence. She will come to your party if you _____her. 

The correct answer is "Option 3" i.e. 'invite'.

 Key Points

• A conditional sentence often involves the term 'if' and indicates the dependency of one event on another.
• In English, this kind of phrases are known as "Real Conditional" phrases (वास्तविक संयोगिता) and are generally used to talk about things which are always true or for future events.
• For example: "He will go for a run if it doesn't rain."
• The correct word 'invite' (आमंत्रित करें) is the base form of verb/infinitive without 'to', used to ask someone politely or officially to do something.
• For example: "You are cordially invited to the inauguration ceremony."

Therefore, the correct answer is - Option 3 "invite".

Additional Information

• 'Will invite' and 'would invite' are incorrect because they are used in future or hypothetical conditions, not in simple present conditions. 
• 'Invited' is incorrect as it is in past tense and doesn't fit in this sentence.
