Edgar was shopping at his local nursery. There, he saw a bag of organic fertilizer that claimed to make the blooms on a flowering plant last twice as long as normal. Edgar was curious whether the fertilizer actually worked, so he conducted the following experiment: Edgar planted two new rose bushes in the same flower bed in his yard. He gave only water to the first rose bush, but he gave water and the fertilizer to the second rose bush. What was the control group for Edgar's experiment?

A.

the second rose bush

B.

the water

C.

the fertilizer

D.

the first rose bush
