Single pass means

A) this algorithm need only onee pass through a data set.
B) This relatively simple learning setting often used in natural language processing.
C) These applications often fit perfectly into the MapReduce abstraction, encapsulating the extraction of local contributions to the map task, then combining those contributions to compute relevant statistics about the dataset as a whole.

A. This algorithm needs only one pass through a data set.

Explanation:

In computing, a one-pass algorithm is a streaming algorithm which reads its input exactly once, in order, without unbounded buffering. A one-pass algorithm generally requires O(n) (see 'big O' notation) time and less than O(n) storage (typically O(1)), where n is the size of the input.

-our input is the dataset
