Which of the following works of Browning are pure dramas?
A) Strafford
B) The Last Ride Together
C) A Blot in the ‘Scutcheon
D) Pippa Passes
E) Porphyria’s Lover
Choose the correct answer from the options given below:

The correct answer is A and C.

To understand why this is the correct choice, let us analyze the nature of the listed works by Robert Browning:
A) Strafford: Written in 1837, this is a historical tragedy in five acts. It was written specifically for the actor William Charles Macready and is one of Browning's earliest attempts at a pure stage drama.
B) The Last Ride Together: This is one of Browning's most famous dramatic monologues, not a play or a pure drama.
C) A Blot in the ‘Scutcheon: Written in 1843, this is a tragic play in three acts. It was also written for William Charles Macready and is classified as a pure drama meant for theatrical performance.
D) Pippa Passes: Published in 1841 as the first volume of his Bells and Pomegranates series, this work is a verse drama or closet drama. While it has dramatic elements, its structure consists of a series of scenes rather than a conventional pure stage drama.
E) Porphyria’s Lover: This is a renowned dramatic monologue (originally published in 1836 as "Madhouse Cells"), not a drama.
Therefore, among the options provided, only Strafford (A) and A Blot in the ‘Scutcheon (C) qualify as pure dramas written for the stage.
