The following data were collected two weeks following reintroduction of Chlorella. (NOTE: "Native" refers to Chlorella originally taken from P. bursaria cytoplasm.)

-Which conclusion is consistent with the data presented in Figure 28.2 above?
A)Co-adaptation between P. bursaria and the native strain of Chlorella has occurred.
B)All types of Chlorella tested are tolerated equally well by P. bursaria.
C)P. bursaria cannot reproduce in the absence of zoochlorellae as well as it can when zoochlorellae are present.
D)Zoochlorellae derived from other protists are well adapted to survive within P. bursaria, relative to the native strain.

The increase in abundance of zoochlorellae two weeks after reintroduction suggests that co-adaptation between P. bursaria and the native strain of Chlorella has occurred.
