Select and explain. 
A. Attitude, B. Value, C. Belief, D. Opinion
A: Attitude
Answer: A: Attitude 
Explanation: Attitudes are acquired characteristics of an individual. They are more or less permanent ways of behaving. An attitude has been defined as a relatively enduring organization of beliefs around an object, subject or concept which pre-disposes one to respond in some preferential manner. Once formed, attitudes are difficult to change. Opinion are views held by people on a point of dispute. Beliefs are permanent, stable, almost unchanging. It is thus easier to give up one's opinions when faced with facts; attitudes and beliefs do not succumb so easily. Ref: Park's Textbook of Preventive and Social Medicine, 19th edition, Page 541-542.
