What happens if you return render() without a context?
In Django, what is the behavior when you call render(request, 'index.html') without providing a context dictionary?
AIt causes a server error because the template expects variables not provided.
BIt raises a TypeError because the context argument is required.
CIt returns a JSON response with empty data.
DThe template renders normally with no variables replaced, as context defaults to an empty dictionary.
