The correct answer is "Heat is given out and ΔH is negative".

Here's why:

An exothermic reaction is a chemical reaction that releases energy by light or heat. This is the form of energy that has an ability to do work, or the transition of energy from one form to another.

In an exothermic reaction, the total energy of the products is less than the total energy of the reactants. Therefore, the change in enthalpy (ΔH), which is the difference in energy between products and reactants, is negative.

So, in an exothermic reaction, heat is given out (energy is released) and ΔH is negative (the energy of the products is less than the energy of the reactants).
