Marley did the following D. Marley screamed a ghostly, fearful scream is the most likely option that caused Scrooge to beg for mercy.
What Marley did
In "A Christmas Carol" by Charles Dickens, the text mentions Marley's scream in the following excerpt: "He raised his hand. Scrooge fell upon his knees and clasped it. 'Dreadful apparition, why do you trouble me?' 'Marley's Ghost... uttered a hollow groan, and rattled its chains so violently that the room re-echoed with the clang of heavy bolts."
Option D is selected because the passage mentions that the scream was "ghostly" and "fearful." This indicates that it was terrifying and unsettling for Scrooge.
The concept of begging for mercy implies fear and desperation. This suggests that the scream triggered a strong emotional response in Scrooge.
