The correct option is
E Agree
'Chime in with means' to interrupt or speak in a conversation, usually to agree with what has been said. Therefore option A, 'agree', is the most suitable answer out of the given options.
The other options are incorrect because 'strike' means to hit, 'approach' means come near or nearer to, 'take away' means a main message or piece of information that you learn from something you hear or read and 'rush off' means to depart in a hurry.
