ii) Let ECR,E # o. Let (i), (i) and (ii) denote the following condition: choose correct. (1) E is infinite (2) E is bounded (3) E is closed (a) 1 is necessary for E to have a limit point. (b) 1 and 2 together are sufficient for E to have a limit point (c) 1 and 3 together are sufficient for E to have a limit point (d) 3 is sufficient for every limit point of E to belong to E
