Option A

Explanation:

In an exothermic reaction, energy is released while in an endothermic reaction energy is taken in. This is because in endothermic reaction, the energy required to break the bonds of reactant molecule is much higher the energy released as of the formation of new bonds in the product.  

Also in an exothermic reaction, potential energy is converted to kinetic energy while in endothermic reaction kinetic energy is converted into potential energy  

Thus, option A is correct

i think so it’s will be b yes i believe its

the correct option is c.

isotopes refers to different forms of the same element with the same atomic number but different mass number as a result of difference in their neutron numbers. isotopes have different relative atomic mass but share the same chemical properties.
