Improve the bracketed part of the sentence. Raj bought an apple (with) a shop.

Answer: 'from'

'From' indicates the source or origin — it shows where something comes from or who provides something.

• You’ll have to borrow the money from someone else.

• She wanted an apology from the president.

• Corrected sentence: Raj bought an apple from a shop.

Why the other choices are not the best fit:

• 'At' indicates location (where something happens). 'Raj bought an apple at a shop' emphasizes the place, whereas 'from' emphasizes the source.

• 'To' is used for direction/destination or to form an infinitive and does not express the source of an item.

• 'With' suggests accompaniment or the instrument used and does not indicate where something came from, so it is incorrect here.
