Rule of zero rationale for resource classes

What does the rule of zero recommend for a class that manages a resource?
Options
  1. 1Always define all five special member functions by hand so every case is handled explicitly
  2. 2Delete the destructor to prevent copying and force the resource to be released only manually
  3. 3Make the class a POD by removing all constructors so it can be copied with memcpy safely
  4. 4Prefer members like smart pointers and containers so no special member functions need to be written
