Which is not true about euglena?

a. they have flagella for locomotion.
b. they are both photosynthetic and saprophytic.
c. they reproduce sexually by conjugation.
d. all of the above are true.

Well, Euglena is in phylum Euglenophyta, and Paramecium is in phylum Ciliophora. You can verify that with a quick Google search.

In short, Your Answer would be Option C
