HTTP Requests & Assertions — quiz

A K6 script needs to send a POST request with a JSON body to create a new user. Which is the correct K6 syntax?

• `http.post(url, body)` — K6 automatically serialises the object and sets Content-Type
• `http.post(url, JSON.stringify(body), { headers: { 'Content-Type': 'application/json' } })` — the body must be serialised and the Content-Type header set explicitly
• `http.request('POST', url, body)` — pass the raw object and K6 serialises it automatically
• `http.fetch(url, { method: 'POST', body: body })` — K6 uses the standard Fetch API
