Correct Answer - Option 1 : widening
A widening conversion changes a value to a data type that can allow for any possible value of the original data. Widening conversions preserve the source value but can change its representation. This occurs if you convert from an integral type to Decimal, or from Char to String.
Widening conversion s a conversion class with no possibility for data loss or erroneous results.
Hence the correct answer is widening conversion.
