D. each table must depend on the entire foreing key
Answer:
The options are not being given. However, we can place the $ sign in front of letter or number we make it constant across the rows or across the columns. By $B we mean, the column will remain same as B as we move across the rows down or up, and by $6 we mean the row will remain fixed to 6 as you move right or left of the cell where you place $6.
Thus, B$6 + C1,will change to below as you move down:
B$6 + C2
B$6 + C3
B$6 + C5
...... and so on.
and if we move left, it will become:
C$6 +D6
D$6 +E6
E$6 +F6
.........and so on.
Please keep an eye on the letter and number, the way they change in each condition, like if its B the next is C irrespective of columns where the next column starts.
