Which of the following describes iambic pentameter?

Iambic pentameter is characterized by having five metrical feet in each line, specifically iambs. An iamb consists of an unstressed syllable followed by a stressed syllable, creating a rhythmic pattern that mimics natural speech. This meter is commonly used in English poetry, notably in works by Shakespeare and other classic poets. By stating that iambic pentameter has five metrical feet, it accurately captures the essence of the term, as "penta-" indicates five and "meter" refers to the measurement of the rhythm within the line. This rhythmic structure helps to create a musical quality in poetry, enhancing both its beauty and its emotional impact.
