JOB_ID VARCHAR2 (10)
Which SQL statement will return the ENAME, length of the ENAME, and the numeric position of the letter "a" in the ENAME column, for those employees whose ENAME ends with a the letter "n"?
A. SELECT ENAME, LENGTH (ENAME), INSTR (ENAME, 'a') FROM EMPLOYEES
WHERE SUBSTR (ENAME, -1, 1) = 'n';
B. SELECT ENAME, LENGTH (ENAME), INSTR (ENAME, -1, 1) FROM EMPLOYEES
WHERE SUBSTR (ENAME, -1, 1) = 'n';
C. SELECT ENAME, LENGTH (ENAME), SUBSTR (ENAME, -1, 1) FROM EMPLOYEES
