Answer: C

Explanation:
Answer C shows correct syntax of command NVL
Incorrect Answers:
A: This command will show ALL data with name substitution of columns shipdate and
total.
B: Incorrect usage for NVL command, because shipdate and total are needed to be
converted into VARCHAR2 type with TO_CHAR function. Both parameters of NVL
command have to have the same data type.
D: Incorrect syntax. TO_CHAR command is used just to convert data type into
VARCHAR2 data type, it have nothing to do with NULL values in columns.
