What is the most suitable continuation to the opinion? Your options are:
A. holding that where state procedural rule was mandatory and unwaivable and where government filed motion to dismiss habeas petition based solely on noncompliance with this procedural rule which state court granted without explanation decision appeared to rest primarily on state law
B. holding that a coa is required to appeal the denial of a rule 60b motion from a judgment in a  2254 proceeding
C. holding that a rule 60b motion ordinarily should be treated as a successive habeas petition but declining to adopt a bright line rule equating all rule 60b motions with successive habeas petitions
D. holding that a rule 60b motion to reopen a habeas denial is barred when its factual predicate deals primarily with the constitutionality of the underlying state conviction or sentence but is permissible when it deals primarily with some irregularity or procedural defect of the habeas proceeding itself
E. holding that appeal from denial of rule 60b motion raised for review only the district courts order of denial and not the underlying judgment itself
