Question 2 Explanation:
The total cost of retrieving records in sorted order using an unclustered B+ tree is given by:
(F + P) * N
Where:
F is the ratio of the size of a data entry to the size of a data record.
P is the average number of records per data page.
N is the number of data pages.
So, the correct answer is (F + P) * N.
(F*N)+P
(F+P)*N
F*N*P
F+P/N
