The general tense of the sentence is past tense('examined'), so the verb should be used in past form. 'swing' is a present form verb, also the use of prompt is incorrect. 'Take another chance' is grammatically incorrect, it should be 'took another chance'; similarly in option (b) too, the use of 'thinks' is incorrect.
