Explanation

Widening conversions convert a smaller primitive type to a larger type without data loss: char to int (16-bit to 32-bit) and short to int (16-bit to 32-bit) are both widening. Options A, D, and E are narrowing conversions (int to short loses precision, double to float and float to long lose range or precision). Widening conversions happen automatically without casting.
