(d) None of the mentioned

This question was posed to me in homework.

This interesting question is from Fundamental of LINQ topic in chapter Delegates, Generics and LINQ of C#

Answer 1

Correct choice is (c) It is not required that linq should make use of IEnumerable interface

Explanation: LINQ at core is the query. A query specifies what data will be obtained from a data source. Query in linq is executed using foreach loop. In order for a source of data to be used by LINQ, it must implement the IEnumerable interface.
