Answer 1

Correct choice is (c) Generic methods are methods that introduce their own type parameters

Explanation: Generic methods are methods that introduce their own type parameters. This is similar to declaring a generic type, but the type parameter scope is limited to the method where it is declared. Static and non-static generic methods are allowed, as well as generic class constructors.
