EMP Table Name Null? Type    
        

EMPNO NOT NULL NUMBER(4)
NAME VARCHAR2(10)
JOB VARCHAR2(9)
MGR NUMBER(4)
HIREDATE DATE
SALARY NUMBER(7,2)
COMM NUMBER(7,2)
DEPTNO NOT NULL NUMBER(2)
TAX Table
Name Null? Type        
TAXGRADE NUMBER LOWSAL NUMBER HIGHSAL NUMBER        

You want to create a report that displays the employee details along with the tax category of each employee. The tax category is determined by comparing the salary of the employee from the EMP table to the lower and upper salary values in the TAX table.
Which SELECT statement produces the required results?
 

Option A

A.    SELECT e.name, e.salary, t.taxgrade FROM emp e, tax t
WHERE e.salary IN t.lowsal AND t.highsal;
 

Option B

B.    SELECT e.name, e.salary, t.taxgrade
FROM emp e, tax t
WHERE e.salary BETWEEN t.lowsal AND t.highsal;
C.    SELECT e.name, e.salary, t.taxgrade
FROM emp e, tax t
WHERE e.salary >= t.lowsal AND <= t.highsal;
D.    SELECT e.name, e.salary, t.taxgrade
FROM emp e, tax t
WHERE e.salary <= t.lowsal AND e.salary >= t.highsal;
 

Option C

C.    SELECT e.name, e.salary, t.taxgrade
FROM emp e, tax t
WHERE e.salary >= t.lowsal AND <= t.highsal;
