Who is credited with the quote, “True friends stab you in the front.”?

The four men in the answer options are all commonly quoted writers.

Oscar Fingal O'Flahertie Wills Wilde (16 Oct 1854 – 30 Nov 1900) was a prolific Irish writer. After writing in different forms throughout the 1880s, he became one of London's most popular playwrights in the early 1890s. He is best remembered for his epigrams and plays, the novel "The Picture of Dorian Gray", as well as the circumstances of his imprisonment and early death.

Known for his biting wit, flamboyant dress and glittering conversation, Wilde became one of the best-known personalities of his day.

At the height of his fame and success Wilde had the Marquess of Queensberry prosecuted for criminal libel. The Marquess was the father of Wilde's lover, Lord Alfred Douglas. The libel trial unearthed evidence that caused Wilde to drop his charges and led to his own arrest and trial for gross indecency with men. After two more trials he was convicted and imprisoned for two years' hard labour, the maximum penalty.

Wilde, in exile in France, died of meningitis on 30 November 1900. Different opinions are given as to the cause of the disease. He was initially buried in the Cimetière de Bagneux outside Paris; in 1909 his remains were disinterred and transferred to Père Lachaise Cemetery, inside the city.
