The correct preposition here is "at".
Because it indicates the location (school) where the social service week is taking place.
The phrase "takes after" means to resemble or inherit traits from someone, typically a parent.
In this context, it implies that he shares characteristics or features with his father.
The correct sentence is "He has no child with his wife.
The preposition "with" is used to indicate the person with whom he shares or lacks children.
The verb "bade" is the past tense of "bid," commonly used to express farewell.
In indirect speech, "Goodbye, my friends" is rephrased to show this form of bidding farewell.
The verb "married" does not require a preposition when used directly with the object.
The correct sentence is:
"Aslam married Salman."
We word complain is followed by to/about.
To & about are prepositions here.
Complain to someone کسی انسان سے شکایت کرنا
Complain about something کسی معاملے پر شکایت کرنا
Salman complained to my father against me.
The correct phrase is "He fell off his horse."
"Off" is used to indicate movement downward from a higher position (e.g., "fall off a bike" or "fall off a ladder").
"In five minutes" means the action will be completed within that time frame.
It's the correct preposition for showing time needed to complete something.
"To" is used to indicate movement toward a place.
So, "We took a trip to town last week" is the correct sentence.
When moving from a higher place to a lower place, we use "down" (e.g., ride down the hill).
So, "I prefer to ride my bike down the hill" is correct.
