题目材料：
Monarch butterflies lay their eggs hundreds of miles away from their places of origin. Each caterpillar that emerges feeds exclusively on milkweed, absorbing the glycosides that milkweed contains. Butterflies retain the glycosides they absorb as caterpillars. Research on monarch butterflies whose migration has been tracked shows that the combination of glycosides in a butterfly always exactly matches the distinctive combination of glycosides that exists in the species of milkweed in the butterfly's place of origin.
If the information provided is true, which of the following is most strongly supported on the basis of it?
-
A.The glycosides present in a monarch caterpillar will generally match those that were present in the butterfly that laid the egg from which the caterpillar emerged.
-
B.Glycosides play an essential role in the biological mechanism that guides a monarch butterfly in its migration.
-
C.The monarch butterflies present in a given region will all contain the same specific combination of glycosides.
-
D.A monarch butterfly does not absorb and accumulate glycosides from the milkweed of regions it reaches as a result of migration.
-
E.Glycosides are the only identifiable substances from milkweed that accumulate in a monarch caterpillar and are retained in the body of the butterfly after metamorphosis.
