Answer : 3. "is described generally, not using a formal definition"
Explanation :
Answer: C) is described generally, not using a formal definition Explanation: In geometry, we can define plane as a flat surface with no thickness. The surface extends with no ends. A plane does not have any edges even if we draw it on paper with edges, it does't mean it has edges. Hence, A plane is an undefined term because it is described generally, not using a formal definition.
