Calling virtual from constructor

Within a base class constructor, a call to a virtual function dispatches to:
Options
  1. 1The base version, because during base construction the dynamic type is the base.
  2. 2The most-derived override, using the not-yet-constructed dynamic type of the object.
  3. 3Undefined behavior, because calling a virtual function during construction is illegal.
  4. 4A pure virtual call, which the standard defines as well-formed and throwing.
