Blank verse is iambic pentameter:

Correct option is A

Blank verse is unrhymed iambic pentameter. It consists of lines with ten syllables, alternating between unstressed and stressed syllables (iambic meter), but does not follow any rhyming scheme. It is widely used in English literature, especially by William Shakespeare and John Milton, for its natural flow and flexibility.
Information Booster:
1. Structure: Blank verse uses a regular meter but avoids rhyme.
2. Notable users: Prominent in works of Shakespeare, Milton, and Wordsworth.
3. Purpose: Provides poetic rhythm while retaining the flexibility of prose.
4. Examples: Shakespeare’s plays (e.g., "To be, or not to be").
5. Versatility: Used in drama, epic poetry, and reflective monologues.
Additional Knowledge:
(B) With rhyme: Incorrect, as rhyming is not a feature of blank verse. (C) With alternate rhyme: Incorrect, as alternate rhyme refers to a structured rhyming pattern like ABAB, which blank verse lacks. (D) Without alternate rhyme: Incorrect, as blank verse is entirely unrhymed, not just lacking alternate rhyme.
