Answer:
There are two correct answers here: C. Shelley and D. Byron.
Explanation:
Terza rima is a type of a stanza that consists of three lines, where the first and the third line will rhyme, whereas the second line will rhyme with the first and third lines of the following stanza. The rhyming scheme will therefore be ABA BCB CDC DED, etc.
Although it was first used by Dante Alighieri in his Inferno, English poets such as Shelley and Byron also wrote their poetry using terza rima: Byron wrote his The Prophecy of Dante and Shelley wrote his Ode to the West Wind, as well as The Triumph of Life in terza rima.
(If you really have to choose only one option, I'd go with Shelley since he used it more often than Byron).
