The correct answer is D. They become able to think logically in abstract situations.
Explanation:
In children development, the concrete operational stage takes place from 7 to 11 years old, during this time children are able to develop logical thinking but only in relation to concrete situation, additionally, they achieve reversibility which refers to numbers and objects being able to return to a former state and conservation that is the idea something might remain in the same state despite other related ideas or objects changing.
This means the one that is not true about the state of concrete operations is that children become able to think logically in abstract situations as during this stage children have difficulties to thnk abstractly and this is only achieved in formal operation stage which occurs after this stage.
Yorktown. Pretty sure this is correct.
