Which of the following is an example of internal attributions? a. telling your parents that the party lasted longer than you thought, which is why you missed curfew. b. believing that your irresponsible attitude and your need to always voice your opinion are the reason that your parents have grounded you. c. none of the options are correct. d. blaming the weather for the school's loss of power.

b. Believing that your irresponsible attitude and your need to always voice your opinion are the reason that your parents have grounded you.

Explanation:

That belief that  you are responsible for something when it's not supported by facts, is an internal attribution.  Maybe there's another reason why you were grounded, we don't know for sure.

Internal attributions always focuses the explanation or the shift of the responsibility onto ourselves, not any exterior factor.

Answer A and D are putting the responsibility/blame on exterior factors than your own, things that are "out of your control", so these are external attributions.
