here, semicolon gives us the lists of things the Agava plant does and parallelism needs to be maintained in the list.
A. that uses most of its energy to produce a single, large, fast-growing flower; dies ---> correct uses, dies and leaves are parellel.
B. using most of its energy to produce a single, large, fast-growing flower; dies ---> Incorrect, as it finishes the sentence and dies has no subject.
C. that uses most of its energy to produce a single, large, fast-growing flower; and then dying ---> uses, "and then dying", and leaves" no parallelism.
D. that, after it uses most of its energy to produce a single, large, fast-growing flower; it then dies --> same as C
E. that as it uses most of its energy to produce a single, large, fast-growing flower; then dies --> same as C
