The correct answer is A. healthy.
A morbid society is one that is characterized by illness, disease, or death. It is a society in which people are constantly sick or dying, and in which there is a general sense of despair and hopelessness.
A healthy society, on the other hand, is one in which people are generally healthy and happy. It is a society in which there is a strong sense of community and cooperation, and in which people are optimistic about the future.
The other options are incorrect because they do not accurately describe a morbid society. A virtuous society is one in which people are generally good and moral. A liberal society is one in which people are generally tolerant and open-minded. A progressive society is one in which people are generally forward-thinking and innovative.
It is important to note that the word “morbid” can also be used in a more figurative sense to describe something that is unpleasant or disturbing. In this sense, a morbid society could be one that is characterized by violence, crime, or other forms of social unrest. However, in the context of the question, the word “morbid” is being used in its literal sense to describe a society that is characterized by illness, disease, or death.
