i think its C.... sorry if its wrong:(((
I believe it is D. Parallelism is used when he says That they, that all that among etc. which creates a rhythm.
This line from <em>Do Not Go Gentle into That Good Night </em>is written in <em>iambic pentameter.
</em>An iamb is a foot (rhythmic unit) of two syllables; the first one being unstressed and the second one stressed. Penta = 5. This means that, in this line, we have 5 sets of iambic feet, which should read like this (lowercase unstressed, capital letters stressed):
<em>
wild MEN who CAUGHT and SANG the SUN in FLIGHT.
</em>This pattern is also supported and used throughout the whole poem.<em>
