Answer:
An iamb consists of a unstressed syllable followed by a stressed syllable.
Explanation:
An iambic pentameter is the metrical form of poetry where there are ten syllables in a line. And the words/ syllables are constructed in the pattern of a unstressed syllable followed by an stressed syllable.
In William Shakespeare's "Sonnet 29", the lines are constructed in the given poem, with the unstressed syllable followed by a stressed syllable. The unstressed syllables are left as is while the stressed syllables are bolded.
<em>"When, </em><em>in</em><em> dis</em><em>grace</em><em> with </em><em>for</em><em>tune </em><em>and </em><em>men’s </em><em>eyes</em><em>,
</em>
<em>I </em><em>all </em><em>a</em><em>lone</em><em> be</em><em>weep</em><em> my </em><em>out</em><em>cast </em><em>state</em><em>,"</em>
Thus, the correct answer is the second option.
