Internal attribution explains behavior as due to which source?

• A. Personal traits
• B. External factors
• C. Personal effort
• D. Lucky circumstances

Answer: (A)

Internal attribution explains behavior by factors inside the person. When you attribute an action to what a person is like—their traits or dispositions—you’re pointing to internal sources rather than the surrounding situation. External factors would be things outside the person, such as the environment or luck. While effort is also internal, the most representative internal source described here is personal traits, which is why that option fits best.
