Some agricultural students conducted a study on the response of a common garden pest to a pesticide. They examined the genetic makeup of the pest and reported the data in the table below. Choose the best conclusion based on the data. [Note: The "X" and "O" represent individuals of the population. The pesticide was applied to Generation 1 and 2.]

A) Between G1 and G2 the individuals all became resistant to the pesticide and in G3 they all continued to survive.
B) Individuals labeled X carry the heritable trait that provides resistance to the pesticide.
C) Individuals labeled O do not carry the heritable trait that provides resistance to the pesticide.
D) The pesticide does not affect the individuals which is why they continue through generations.
E) In G1 the Xs that do not contain the heritable trait of resistance died; in G2 those with the trait reproduced, so that by G3 only individuals with the trait survived.
