Answer 2

D. A duck flies to another pond.

The above sentence is an example of emigration. Emigration refers to moving from one area to another for a long or permanent period. In this instance, a duck is leaving the pond it originally resided in (along a population other ducks) in order to reside in another pond. Therefore, it can be said that the duck "emigrated".
