Answer
The elements up to $A\approx56$ (the peak of the binding energy curve) can be "cooked up” by thermonuclear fusion processes in stellar interiors.
In the given elements, the values of $A$ for carbon is 12, for silicon 28, for chromium 52, and for bromine is 80. Therefore, the element "bromine" is not “cooked up” by thermonuclear fusion processes in stellar interiors.
