Which of the Following Pairs of Reproductive Strategies Is Consistent

Which of the following pairs of reproductive strategies is consistent with energetic trade-off and reproductive success?

A) Pioneer species of plants produce many very small, highly airborne seeds, whereas large elephants that are very good parents produce many large offspring.
B) Female rabbits that suffer high predation rates may produce several litters per breeding season, and coconuts produce few fruits, but most survive when they encounter proper growing conditions.
C) Species that have to broadcast to distant habitats tend to produce seeds with heavy protective seed coats, and animals that are caring parents produce fewer offspring with lower infant mortality.
D) A free-living insect lays thousands of eggs and provides no parental care, whereas a flowering plant takes good care of its thousands of seeds until they are ready to germinate.
E) Some mammals will not reproduce when environmental resources are low so they can survive until conditions get better, and plants that produce many small seeds are likely found in stable environments.
