Step 1: Conceptual Overview:
This query pertains to Raymond Cattell's trait theory of personality, which distinguishes between two trait levels:
Surface Traits: Observable, numerous behavioral patterns stemming from source trait interactions.
Source Traits: Fundamental, underlying personality structures that are fewer in number and drive consistent behaviors.
Step 2: Detailed Analysis:
Evaluating the provided options based on Cattell's theory:
(A) stable: Source traits represent the core, enduring aspects of personality, making this statement accurate.
(B) result of the interaction between surface traits: This is incorrect; surface traits are the result of source trait interactions.
(C) considered as the building blocks of personality: Source traits are recognized as the foundational elements of personality construction, rendering this statement accurate.
(D) quite generalised dispositions: This description better fits surface traits, which are more generalized and observable behavioral clusters.
Step 3: Conclusion:
Statements (A) and (C) accurately describe source traits. Consequently, option (3) is the correct choice.
