Return type is bool. A, B, D return not bool.

very interesting. very well spotted by Artem. these are method based queries i.e extension methods.
these methods extend any variable that implements the Ienumerable interface. method based queries take a lamba expression as a parameter which represents the logic to be performed while enumerating through the sequence.
Return type is bool. A, B, D return not bool.
all are valid but Return type is bool. A, B, D return not bool.
