Answer 1

Answer)

1) A) main-title { text-size: 1em; }

As we don't have the value provided to be displayed hence the output to be displayed would be as mentioned above

2) c)a column name

This would return the complete SUM of the numeric columns

3) c)foreign key

As per the rule, it is the primary key of one table to be combined with the foreign key of the other to form a JOIN of the tables
