(b)Etiology
(c)Traumatology
(d)Trichology

Answer 1

Hint: This word is used by doctors and medicinal fields to refer to the origin or causation of a particular disease or disorder. This word has originated from Greek.

Complete answer:
The study of diseases is called pathology, while the specific study of the causes of a disease is known as Etiology. The term etiology is derived from the Greek ‘aitiología’ which translates to "giving a reason for". The word etiology can also refer to the study of the causes of things in other fields too, such as philosophy and physics.

Additional Information:
 In humans, the term disease is often used to broadly refer to any condition that can cause pain, dysfunction, social problems, distress or sometimes even death to the afflicted person, or similar problems for people in contact with that person.
Diseases can affect people not only physically, but sometimes they also affect a person mentally, as contracting and living with a fatal disease can alter the affected person's perspective about life.
For various reasons like helping a person to cope up with this condition to treat a disease, it is very important to know the causes of a particular disease. Some diseases like COVID-19 or Influenza are infectious and hence it is important to know the cause to both treat the patient and to protect the people in contact with the affected person.
This study of causes of a disease is known as Etiology.

So, the answer is, ‘ Etiology.’

Note: Knowing the etiology of a disease is the first step towards the treatment of a disease or investigation of disease.
Etiology studies both intrinsic and extrinsic causes of diseases.
Intrinsic causes can be genetic diseases, cancerous changes, associated diseases like diabetes or heart problems, or sometimes weak immunity. These are the causes that are associated with the affected person.
Extrinsic causes include an infectious carrier, other patients, specific diet, or sometimes even due to the errors committed by the doctor(Iatrogenic causes).
