Identify key concepts related to configuring Discoverer

Examine this block of code:
SET OUTPUT ON
Declare
X NUMBER;
V_SAL NUMBER;
V_found VARCHAR2(10):='TRUE';
Begin
X:=1;
V_sal := 1000;
Declare
V_found VARCHAR2(10);
Y NUMBER
Begin
IF (V_Sal>500) THEN
V_found := 'YES';
END IF;
DBMS_OUTPUT.PUT_LINE('Value of V_found is '|| V_Sal);
DBMS_OUTPUT.PUT_LINE('Value of V_Sal is '|| TO_CHAR (V_Sal));
Y:=20;
END;
DBMS_OUTPUT.PUT_LINE('Value of V_found is' || V_found);
DBMS_OUTPUT.PUT_LINE('Value of Y is' || TO_CHAR(Y));
END;
SET server OUTPUT if
What is the result of executing this block of code?

A. PLS-00201: identifier 'Y' must be declared.
B. Value of V_found is YES
Value of V_sal is 1000
Value of V_found is TRUE
C. Value of V_found is YES
Value of V_found is 1000
Value of V_found is TRUE
Value of Y is 20
D. PLS-00201: identifier 'V_sal' must be declared
PLS-00201: identifier 'Y' must be declared
E. Value of V_found is YES
Value of V_sal is 1000
Value of V_found is TRUE
Value of Y is 20

Answer: A

Explanation:
Answer A is correct because PL/SQL variable 'Y' is not declared in DECLARE section of
PL/SQL block, but only inside BEGIN ... END block and executing of this block will
return error.
Incorrect Answers:
B: This code does work because of V_found and V_sal are identified.
C: This code does work because of V_found and V_sal are identified.
D: Identifier V_sal is declared, so code will fail because of identifier 'Y', not V_sal, must
be declared.
E: This code does work because of all variables are declared and populated with values.
