execute() returns a Promise that immediately calls reject(). So promise starts in a rejected state.

When a Promise is rejected and you chain .then() calls without rejection handlers, all those .then() callbacks are skipped until a .catch() is encountered:

promise

then(...) // skipped

then(...) // skipped

then(...) // skipped

catch(...) // executed

then(...); // executed after catch

Execution:

.then(() = > console.log( ' Resolved1 ' )) is skipped.

.then(() = > console.log( ' Resolved2 ' )) is skipped.

.then(() = > console.log( ' Resolved3 ' )) is skipped.

.catch(() = > console.log( ' Rejected ' )) runs and logs Rejected.

The .catch() returns a resolved Promise (no explicit return, so undefined), so the next .then() runs:

.then(() = > console.log( ' Resolved4 ' )) logs Resolved4.

Final output:

Rejected

Resolved4

This matches option D.

The syntax:

import printPrice from ' module ' ;

means the module must export its function as a default export :

export default function printPrice() { ... }

Why the others are wrong:

Named exports require curly braces:

import { printPrice } from ' module ' ;

“all export” and “multi export” are not JavaScript terms.

Therefore, printPrice must be the default export .

JavaScript Knowledge References (text-only)

Default imports use: import name from ' module ' .

Named imports require braces: import { name } from ' module ' .

fullName is defined as a getter :

get fullName() { ... }

Getters are accessed like properties , not like functions.

So:

cat.fullName; // " Fancy Whiskers "

No parentheses.

Why others are wrong:

A: cat.fullName() tries to call the returned string as a function.

B and C: These properties (get, function) do not exist; they are misinterpretations of syntax.
