To provide an accurate answer regarding the impact of the image on the American colonists, additional context about the image is necessary. However, based on common historical interpretations of engravings from that period, the fourth option seems likely to be the most accurate:
"By confirming the repressive actions of the British government, the engraving would increase the desire to rebel against it."
Many engravings during the lead-up to the American Revolution depicted British actions in a negative light, which often fueled anti-British sentiment and increased support for the revolutionary cause among colonists.
