Answer:
The correct answer to the following question will be Option B.
Step-by-step explanation:
The president says in his speech that "Rational thinking calls on us to work together in concert." For such a reason, fighting wars, breaking diplomatic ties or stopping trade with China because they claim they will have to collaborate would not make sense.
Barack Obama in his speech neglects to mention China as an adversary or as a possible threat. He admits only that China is the other biggest energy user. Also, the US's relationship with China is peaceful and stable, though complex.
Therefore, Option B is the right answer.
