Which of the following works is NOT written by P. B Shelley?

The correct option is The Vision of Judgement.

To determine which work was not written by Percy Bysshe (P. B.) Shelley, we can examine the authorship and background of each option:
1. The Vision of Judgement (published in 1822) was written by Lord Byron (George Gordon Byron). It is a famous satirical poem written in response to Robert Southey's poem A Vision of Judgement, which praised King George III. Because it was written by Byron, it is NOT a work by P. B. Shelley.

The other three options are well-known works by P. B. Shelley:
