a. { } b) ( ) c) [ ] d) < >



​

Answer 1

Parenthesis ( ) - Option b

is mandatory to write the type annotations in the function definition.

Explanation:

In general notation, the function definition's structure is:

function_keyword/return_type function_name ( type parameter, type parameter...)

{

body

}

To take in the typed arguments or parameters, the definition of the function holds them within the parenthesis () to tell the compiler that those are the parameters that are sent on call for their usage within the function.

So, the answer is Parenthesis ()
