The correct answer is A. Diseased.
Morbid is an adjective that means “characterized by or suggestive of illness or death.” It can also mean “having an unhealthy interest in death or
disease.”Diseased is an adjective that means “affected by disease.” It can also mean “in a state of decay or decomposition.”
Dying is an adjective that means “in the process of dying.” It can also mean “coming to an end.”
Irritated is an adjective that means “feeling or showing annoyance or impatience.” It can also mean “causing annoyance or impatience.”
Angry is an adjective that means “feeling or showing anger.” It can also mean “causing anger.”
In this case, the word “morbid” is most closely associated with the word “diseased.” This is because both words refer to something that is unhealthy or diseased. The other words, “dying,” “irritated,” and “angry,” do not have the same meaning as “morbid.”
