He tried to open the tin . . . . . . . . a knife. A. by B. with C. out of D. from

The correct answer is: B. with

The word “with” is used to indicate the instrument or tool that is used to perform an action. In this case, the action is “opening the tin” and the instrument is “a knife”.

The other options are incorrect because:

• “By” is used to indicate the means or method by which an action is performed. In this case, the means or method is not specified.
• “Out of” is used to indicate the source or origin of something. In this case, the source or origin of the tin is not specified.
• “From” is used to indicate the starting point of a journey or movement. In this case, the starting point of the action is not specified.
