Explanation:

The option that best defines a couplet is that a couplet is two consecutive rhyming lines. The word couplet originates from a similar word, couple, which means 2 things. So obviously, a couplet would also incorporate only two things, so you can dismiss options A and C. D is also incorrect, as that is not a couplet, but rather a trochee.
