A group of scientists studied seismic waves and observed that the waves were bent. Based on the scientists' observations, it can be concluded that the seismic waves may have bent due to Earth's gravitational field
bent due to Earth's magnetic field
passed through the Earth's core
passed through the mantle

The answer is not D

it should be all of them because it asks if you included all of those in your answer

explanation:

a. energy is absorbed in the reaction.

if in a given reaction the energy of products is greater than the energy of reactants it means that reaction is endothermic and during the reaction, the energy is absorbed by reactants. in an endothermic reaction, the products have more stored chemical energy than the reactants. and in this reaction the reactants are more stable than products before the compounds with less energy are always more stable.

the answer your looking for is c).
