Step 1: Understanding the Concept:
Personality means the stable and unique pattern of a person's thoughts, feelings and behaviour. We must decide which of the four statements describe it correctly.
Step 2: Key Formula or Approach:
Recall the main features of personality: it has body and mind parts, it is dynamic, it is organised, and its expression is unique to each person. It is also fairly stable over time.
Step 3: Check statement (A).
Personality includes both physical parts (such as body build and health) and psychological parts (such as traits and motives). So (A) is TRUE.
Step 4: Check statement (B).
Personality is fairly stable over time. It does not change easily. So (B) is FALSE.
Step 5: Check statement (C).
Personality is dynamic. Some features can shift with the demands of a situation. So (C) is TRUE.
Step 6: Check statement (D).
Each person shows a fairly unique pattern of behaviour. So (D) is TRUE.
Step 7: Choose the option.
The true statements are A, C and D. That is option (2). Options (1) and (4) include B, which is false. Option (3) leaves out A, which is true.
Final Answer:
Statements A, C and D are correct, so the answer is option (2).
\[ \boxed{\text{A, C and D only}} \]
