Answer:
c). Free verse
Step-by-step explanation:
'Free verse' is characterized as the poetic form in which the lines are divided without any particular length or meter and without having a rhyme scheme. Such a poetic form offers complete liberty of word choice to convey the intended idea or meaning to the readers. Such a poetic structure allows a greater opportunity to interpret the poem as per their experiences.
T.S. Eliot's poem 'Preludes' is written in free verse as it neither follows a specific rhyme scheme nor a particular length, meter, or pattern. All the six stanzas in the poem follow distinct patterns and have unevenness throughout. Due to this inconsistency, it falls into the category of 'Free Verse.' Thus, option c is the correct answer.
