Fill in the blanks with a suitable preposition.
The dish was created _______ the head chef _______ strawberries.
The prepositions ‘by’ and ‘with’ are used to denote the manner in which an action is performed. ‘By’ is used to refer to the person or people who perform something, while ‘with’ is used to refer to the tools or material used for performing something. In the given sentence the agent of the action is 'the head chef' whereas 'strawberries' are the material used to create the dish. Therefore option B is correct, while option A is incorrect. On the other hand ‘for’ cannot be used in the second blank because ‘for’ is used to denote for whom something is created. The dish was not made for 'strawberries', therefore options C and D are incorrect.
