Step 1: Concept. Rotter’s locus of control describes whether outcomes are attributed to one’s own actions ({internal}) or to external forces like luck/chance ({external}).
Step 2: Evaluate options.
(A) True. By definition there are internal and external loci; people vary along this continuum (domain-specific mixes are possible).
(B) True. Internals typically show higher perceived control and are moderately associated with higher self-esteem.
(C) True. Internal LoC correlates positively with academic/job success, proactive coping, and persistence.
(D) False. Feelings of regret and attributional style are related: those with a stronger internal LoC often experience regret tied to personal responsibility, showing {an association}. Hence the statement “no association” is incorrect.
Conclusion: (A), (B), and (C) are correct; (D) is not.
