Database table by name Loan_Records is given below. What is the output of the following SQL query?SELECT count(*) FROM ( (SELECT Borrower, Bank_Manager FROM Loan_Records) AS S NATURAL JOIN (SELECT Bank_Manager, Loan_Amount FROM Loan_Records) AS T );

Let us evaluate the subqueries:

1. Table $S$ (Borrower, Bank_Manager):

   • (Ramesh, Sunderajan)

   • (Suresh, Ramgopal)

   • (Mahesh, Sunderajan)

2. Table $T$ (Bank_Manager, Loan_Amount):

   • (Sunderajan, 10000.00)

   • (Ramgopal, 5000.00)

   • (Sunderajan, 7000.00)

3. Natural Join on Bank_Manager:

   • For Bank_Manager = 'Sunderajan': Table $S$ has 2 rows and Table $T$ has 2 rows, producing $2 \times 2 = 4$ tuples:

     • (Ramesh, Sunderajan, 10000.00)

     • (Ramesh, Sunderajan, 7000.00)

     • (Mahesh, Sunderajan, 10000.00)

     • (Mahesh, Sunderajan, 7000.00)

   • For Bank_Manager = 'Ramgopal': Table $S$ has 1 row and Table $T$ has 1 row, producing $1 \times 1 = 1$ tuple:

     • (Suresh, Ramgopal, 5000.00)

4. Total row count:

   $$\text{Total rows} = 4 + 1 = 5$$

Thus, SELECT count(*) returns 5 (Option C).
