The appropriate preposition to fill in the blank in the sentence is "with."

So the complete sentence would be: "Sheena and her friends quarreled with the shopkeeper over the price of a camera."

Explanation:

The preposition "with" is used in this context to indicate involvement or a relationship in the action of quarreling. When people have conflicts or disagreements, the word "with" usually denotes the parties involved in the dispute. In this case, Sheena and her friends are having an argument "with" the shopkeeper regarding the camera's price, highlighting an active engagement in the disagreement. Other prepositions such as "about" or "over" can also be used in conjunction with "with" to elaborate on the subject of the quarrel, but "with" is the key preposition that directly connects the subjects of the quarrel.
