A. To prevent unwanted implicit conversions
Answer: (A) To prevent unwanted implicit conversions
The explicit keyword can be used with a constructor to prevent certain unwanted implicit conversions.
For example, a single-argument constructor can otherwise sometimes be used for implicit conversion from the argument type to the class type.
Declaring the constructor as explicit requires the programmer to explicitly create the object instead of allowing such implicit conversion.
This improves type safety and makes the programmer's intention clearer.
