Question 111 of DSSSB TGT Computer Science PYQ, 24 Jun 2023, Shift 3 (4:30 PM)

Show answerHide answer
Correct answer: (D) 2, 3 and 5
Explanation
Removing vertex 2 splits {1, 3, 4, 9, 10} from {5, 6, 7, 8}, removing 3 cuts off 9 and 10, and removing 5 cuts off 6. Vertices 1, 4, 7 and 8 lie on cycles, so the articulation points are 2, 3 and 5.
