The correct answer is D. deliberately.
The word
“cold blood” means without feeling or mercy. It is often used to describe a murder that is premeditated and carried out without emotion. In this case, the dacoit murdered the man in cold blood, meaning that he planned the murder and carried it out without any remorse.The other options are not as accurate descriptions of the dacoit’s actions. Option A, “coldly,” could be used to describe the dacoit’s demeanor during the murder, but it does not necessarily mean that he planned the murder or carried it out without emotion. Option B, “boldly,” could be used to describe the dacoit’s actions in general, but it does not necessarily mean that he murdered the man in cold blood. Option C, “ruthlessly,” could be used to describe the dacoit’s actions, but it does not necessarily mean that he planned the murder or carried it out without emotion.
Therefore, the correct answer is D. deliberately.
