What is the output of the following JavaScript code?

const o = {a: 1, b: {c: 2}};
const p = {...o};
p.b.c = 9;
p.a = 5;
console.log(o.a, o.b.c);

Correct answer: B

Explanation

The spread creates a shallow copy: p.a is an independent value, but p.b is the same nested object as o.b, so only o.b.c changes.
