The correct answer is A. uncultured.
The officer incharge was quite humane in his approach. This means that he was kind and compassionate, and he treated the people he was in charge of with respect.
Uncultured means not having or showing the knowledge, experience, and understanding that is expected of a person of a particular social class or level of education. This is the opposite of what the officer incharge was doing, as he was showing kindness and compassion to the people he was in charge of.
Unsympathetic means not feeling or showing sympathy for someone or something. This is also the opposite of what the officer incharge was doing, as he was showing kindness and compassion to the people he was in charge of.
Uncivilised means not having or showing the qualities of a civilized person, such as good manners, respect for others, and a sense of justice. This is also the opposite of what the officer incharge was doing, as he was showing kindness and compassion to the people he was in charge of.
Uncompromising means not willing to change one’s mind or position, even when faced with strong arguments or evidence to the contrary. This is not necessarily the opposite of what the officer incharge was doing, as he may have been willing to change his mind or position if he was presented with strong arguments or evidence to the contrary. However, it is not something that is explicitly mentioned in the question, so it is not the best answer.
