B Correct answer

The Aggregator stage produces double precision floating point numbers by default for aggregated values like SUM, AVG, MIN, MAX. Using double precision prevents rounding errors and maintains accuracy for decimal calculations. Single precision or integer would lose precision for most aggregations involving division or decimals.
