Answer: B
Reasoning: Column input is used when data fields are fixed. In this
situation, the columns can be read in any order and re-read if
necessary. Missing data does not require a placeholder either.
Unfortunately, only standard data should be read using column input:
nonstandard data should utilize the formatted input.
