is a special value that cannot be mistaken as a member of a list of data items and signals that there are no more data items to be processed. A. Sentinel B. Accumulator C. delimeter D. terminator

Answer: A) Sentinel

Explanation:

Sentinel is considered as special values that has the ability to act for termination or stopping the loop or condition in algorithms. It is also known as flag value. It is not considered as the member of data object present in the list of program or algorithm.

Other options are incorrect because accumulator, terminator and deliminator are not the values that can use itself in algorithm to terminate a condition. Thus, the correct option is option (A).
