int j=18;
int sum=0;
for (int i =1; i<7; i++)
{
sum=sum+(i*(j-2));
j=j-2;
}
System.out.println(sum);
}
}
Explanation:
<u>Variables used: </u>

(a) There will be a need for the database to support a comparatively complex and complicated hierarchical internal record structure that may vary for each record. Column store NoSQL DBMS
(b)The key requirements for the database are to access a specific record structure as quickly as possible without any concern regarding the internal structure of the record. Key value store NoSQL DBMS
(c) The data are specifically well suited to be organized as a network of connections amid the data items. Graph Base NoSQL DBMS
(d) It is essential that the DBMS offers quick access to each of the records by a key value, but, in addition, it has to also allow easy access to the components of each record. Document store NoSQL DBMS
I'm pretty sure the answer is b
