Which type of meter consists of one stressed and one unstressed syllable?

The type of meter that consists of one stressed and one unstressed syllable is iambic. In iambic meter, the pattern begins with an unstressed syllable followed by a stressed one, creating a rhythmic flow that is often found in English poetry. This rhythm mimics the natural cadence of speech, making it both relatable and pleasing to the ear. This structure is famously employed in works such as Shakespeare's plays and sonnets, contributing to its popularity in English literature.

The other options represent different metrical patterns: spondaic meter consists of two stressed syllables, dactylic meter has a stressed syllable followed by two unstressed syllables, while trochaic meter starts with a stressed syllable followed by an unstressed one. Each of these has distinct rhythmic characteristics that differentiate them from iambic meter.
