Which is true of non flowering plants?

They all reproduce asexually.
They all reproduce sexually.
They are unable to reproduce.
Some reproduce sexually and some reproduce asexually.

Some reproduce sexually and some reproduce asexually.

Are you sure

I apologize for the previous response. The correct statement is: Some reproduce sexually and some reproduce asexually.

Is that right

Yes, that is correct. Some non-flowering plants reproduce sexually through spores or other means, while others reproduce asexually through mechanisms such as fragmentation or vegetative propagation.
