The answer is A, as others have put, the -> symbols cannot be used in a function like this, only =.

You're right, as a general rule, lambda functions cannot be named

Yep it is A. The only issue I saw on option A is that ""productCategory" is defined as "string" instead of "String" ( 's' instead of Capital S). However, if I also define a custom type (type string = String ) , it works fine . I just tried . so it is A the right answer .
