To answer this question, we need to understand how division by zero is handled in DataStage 8.5.
In DataStage 8.5, if division operation has to be performed in the Transformer stage, and the numerator is 1 while the denominator is 0, the output will be zero.
The correct answer is A) Zero.
This is because in DataStage 8.5, dividing any number by zero results in zero. It does not throw an error or abort the job.
