Who among the following in the article. “Fleshly school of poetry”. Attacked the pre-Raphaelites, especially D.G. Rossetti?

The correct option is Robert Buchanan.

Explanation:
"The Fleshly School of Poetry" is the title of an essay published in The Contemporary Review in October 1871 under the pseudonym "Thomas Maitland". The real author of this article was the Scottish poet and novelist Robert Buchanan.
In this article, Buchanan launched a scathing literary attack on the Pre-Raphaelite Brotherhood, targeting Dante Gabriel Rossetti (D.G. Rossetti) in particular. He accused them of being morbid, sensuous, and emphasizing bodily pleasures and physical details over spiritual or moral values. Rossetti famously replied to this criticism with his own essay titled "The Stealthy School of Criticism," defending his poetic style.
