An ASBR-Summary-LSA describes the route to an ASBR but is advertised to all related areas except the area to which the ASBR belongs, making the statement false. An ASE-LSA describes the route to an external AS, but it is not flooded to another AS, making this statement false as well. The metric of a Type-1 external route includes both the internal cost to reach the ASBR and the external cost from the ASBR to the external destination, contradicting the statement that it is only the AS external metric. Thus, statements A, B, and D are false.
