Concept:Metre is the systematic pattern of stressed syllables that produces rhythm in poetry.
Explanation:Metre is the regular beat created by the arrangement of stressed and unstressed syllables.
Each metrical unit, called a foot, combines syllables in fixed patterns such as iambic or trochaic.
When a poem is read aloud, this recurring beat gives it a musical flow.
That flow is what we call rhythm.
A stanza is a grouped set of lines, not a rhythmic pattern.
Rhyme involves identical or similar sounds at line endings, not the beat itself.
Verse refers to a single line or poetry in general.
Therefore, metre directly expresses the idea of rhythm in a poem.
Answer:The idea of metre is rhythm, so the correct option is B.
