Out of that list, the concave mirror is the only item that can concentrate sunlight and heat into a small area. But if you could get ahold of a convex lens, that would be even better.

Answer: Concave mirror would be best to use.

Explanation :

To focus sunlight to ignite a pile of twigs for a campfire, a concave mirror should be used.

When the rays of light coming from infinity parallel to principal axis in front of a concave mirror, all the rays get concentrated at the focus of the mirror. That's why the concave mirror is also known as converging.

In this case, a concave mirror should be used so as to converge all the rays at a point.
