Afunction template argument list can contain
a. only parameterized types
b. only nonparameterized types
c. any combination of parameterized and nonparameterized types
d. either parameterized or nonparameterized types, but not both in the same argument list

c) Any combination of parameterized and non-parameterized types

Explanation: Function template can have the function parameter in the list.These parameters are used for passing the arguments.Function template can pass parameterized argument like function value and a non-parameterized argument which has not parametric value.

Other options are incorrect because no two same parameterized value or non parameterized value can be passed togather in the same list of argument.. Thus, the correct option is option(c).
