Compare the most likely cause of death for an individual born in 1900 and an individual born in 2006.

The most likely cause of death in 1900 would be pneumonia/influenza, while the leading cause of death in 2006 was heart disease.

so we know the answer cannot be c because no insect or animal starts as an adult

the answer is a. a swimming larvae

because since they are sea animals they automatticaly have to know how to swim they cannot just sink to the bottom

sorry if this is the incorrect answer.
