Question 31

+3 marksOne correct option

Prashant and Nikita are creating a quiz question paper collaboratively. They are each working on different sections — and complete their tasks in parallel. Meanwhile, Mayur is enjoying a single- player game that finishes when the game loop ends.
To compare productivity:
● If Prashant and Nikita (together) finish faster than Mayur, the winner is "Team".
● If Mayur finishes faster, he wins.
● If both take the same time, Mayur wins by default.
You are simulating this scenario in the browser.Prashant and Nikita are represented using parallel Promises. Mayur is represented using a single Promise. The frontend must calculate who finishes first using asynchronous logic, and display the result.

app.js

javascript

1function simulateTasks() {
2  const prashant = new Promise(resolve => setTimeout(() =>
3resolve("Prashant"), 3000));
4  const nikita = new Promise(resolve => setTimeout(() =>
5resolve("Nikita"), 2000));
6  const mayur = new Promise(resolve => setTimeout(() =>
7resolve("Mayur"), 4000));
8
9  const team = Promise.all([prashant, nikita]).then(() =>
10"Team");
11
12  Promise.race([team, mayur]).then(winner => {
13    console.log("Winner is:", winner);
14  });
15}

Based on the above data, answer the given subquestions.

If Prashant and Nikita finish together in 3 seconds (since Promise.all waits for both), and Mayur finishes in 4 seconds, who wins?

A
Mayur
B
Team
C
Nikita
D
Race condition prevents output
