Answer:(d) MyISAM

e) InnoDB

Explanation: MyISAM is type of default engine storage in table form in MySQL 5.5.It is discontinued and no longer available service.It had the feature of creating a backup, able to create replicas,data dictionary automatic updates etc in table.

InnoDB took over on the place of MyISAM in MySQL 5.5 as the default engine storage when MyISAM was discarded. It has the capability to support foreign keys, tablespaces, operation of spatial nature etc.

Other options are incorrect because black-hole is mechanism of data packet destruction without the acknowledgement of sender, supernova is type of computer unit and memory is the operating unit part where the data storage takes place.Thus the correct options are (d) and (e).
