D Correct answer
Explanation

ResultSet provides type-specific getter methods like getString(), getInt(), getBoolean() to retrieve column values by column name or index. The methods handle type conversion automatically. Options A, B, and C describe non-existent methods - there is no generic get() or getValue() method in ResultSet.
