Which statement about implicit type casting is true?

Which statement about implicit type casting is true?

• A. It automatically converts types in expressions
• B. It always requires explicit casting
• C. It sometimes converts types but not always
• D. It does not apply to arithmetic operations

Answer: (A)

Implicit type casting is automatic conversion of a value from one data type to another within an expression, done by the language without you writing a cast. It happens when the language can safely promote to a compatible type, so expressions like mixing an int with a double automatically use the higher-precision type. That’s why this statement is true: the conversion happens automatically as you evaluate the expression. The other ideas don’t fit because implicit casting doesn’t require explicit casts in safe cases, it does apply to arithmetic operations when different numeric types are involved, and it’s about automatic promotions rather than blocking them.
