In a line of the poem, an iamb is referred to as the unstressed syllable but it is frequently followed by the stressed syllable. In short term, it can be understood as the iamb is the short syllable that is often followed by the long syllable.
The correct answer is A. In fair Verona, where we lay our scene.
The reason for the correct answer:
Option A. In fair Verona, where we lay our scene is correct because these lines are showing the short syllable followed by the long syllable and therefore these lines are examples of iambic pentameter.
The reason for the wrong answers:
Options:
B. Speaking of worth, what worth in you doth grow.
C. Fire burn and cauldron bubble.
D. Tomorrow, and tomorrow, and tomorrow.
These options are wrong because these options are not showing the short syllable that is often followed by the long syllable and hence these are not part of the iambic pentameter.
