Multiple choiceHardchapter-1-curatedpremiumcore-javavariables-and-data-types
Answer and explanation
Correct answer
D. BigDecimal, for precision

BigDecimal is designed for precise calculations, such as those involving currency, as it avoids the precision errors associated with floating-point types like 'double'. 'int' and 'long' do not support decimal values, and 'double' may introduce rounding errors.
