The right answer is the D: Three quatrains and a couplet. This is an example of a sonnet. It features, on the one hand, three quatrains, or four-line stanzas rhyming ABBA. This type of rhyme is called envelope or enclosed:
<em>Whoso..... HIND</em> (A)
<em>But.... MORE</em> (B)
<em>The vain... SORE</em> (B)
<em>I am... BEHIND</em> (A)
On the other hand, it features a couplet, which is a pair of successive rhyming lines:
<em>"Noli... AM </em>(C)
<em>And... TAME</em> (C)
