A developer has a module that contains multiple functions.

The correct answer is D .

When a module contains multiple functions and each function should be available individually, the best choice is a named export .

Example:

function add(a, b) {

return a + b;

}

function subtract(a, b) {

return a - b;

}

export { add, subtract };

Then another file can import exactly the functions it needs:

import { add, subtract } from ' ./mathUtils.js ' ;

console.log(add(5, 2));

console.log(subtract(5, 2));

Named exports are useful when a module provides several reusable functions, constants, or classes.

Why the other options are incorrect:

multi is not a JavaScript export type.

default is usually used when a module has one main value to export. A module can only have one default export.

all is not an export type in JavaScript module syntax.

Therefore, the correct export type for multiple functions is named export , so the verified answer is D .
