Consider a join (relation algebra) between relations r(R)and s(S) using the nested loop method. There are 3 buffers each of size equal to disk block size, out of which one buffer is reserved for intermediate results. Assuming size (r(R)) < size (s(S)), the join will have fewer number of disk block accesses if

Option A. relation r(R) is in the outer loop.
Option B. relation s(S) is in the outer loop.
Option C. join selection factor between r(R) and s(S) is more than 0.5
Option D. join selection factor between r(R) and s(S) is less than 0.5
True Answer A

Explanation :

 A join between r(R) and s (S) using nested loop method will be as follows.
For each tuple r in R do
For each tuple s in S do
If r and s satisfy the join condition then output the tuple <r,s>
This algorithm will involve  block transfers and  seeks, where  and  are number of blocks in relations R and S respectively and nr is number of tuple in relation R. Now to have less block accesses,  should be less and it is already given that |R|<|S|. Relation r(R) should be in the outer loop to have fewer number of disk block accesses.
