Answer:
B. Meter and alliteration are less important today.
Explanation:
14th century poetry had an obsession with the use of meter and rhyme schemes. The writers and poets were specific of the meter and literary devices that gave an artificial feel to the poem contrary to contemporary poetry which doesn't pay much attention to meter and rhymes as it is more inclined to be written in free-verse. The most intriguing feature of modern poetry is that it offered freedom and liberty to the authors to express their ideas freely unlikely to 14th century poets who were restricted due to these meters and rhyme schemes. Thus, option B best illustrates the transition.
