Answer: Option B

Explanation:

A non native species is greatest threat to biodiversity. The species that are not present in the particular place and are introduced in the biodiversity by any means whether it is intentional or unintentional is known as invasive species or non native species.

The non native species of bees is introduced to prey on the fire ants can be a threat to biodiversity as it can use the resources available for the native species.

The effect of the non native species on the native species is not predictable on the species that is already present there.
