In his experiments with different competing pairs of Paramecium species, Gause found that sometimes both species persisted and sometimes only one species did. Which hypothesis did Gause propose in order to explain the cases in which both species persisted?

The options are not given, here are the options.

A. One species is much better competitor than the other.

B. Periodic disturbances allow for coexistence.

C. Two species tended to use different resources.

D. The two species experienced interference competition and not exploitative competition.

The correct option C.

Two species tended to use different resources.

Explanation:

From Gause experiments on competing paramecium pairs, He found out that most times both species persisted and sometimes only one did because the two species uses different resources.

Organisms normally compete for limited resources in order to survive and one intend to compete well while other suffer. Both in the case of competing paramecium pairs, the pair use different resources which make the to persist and survive well. Once the resource of one finishes, the other one will persist because it is still surviving on its available resources.
