d) very tired and coming down to rest

Explanation:

The momentum of an object is defined to be the product of the object and its velocity. So in the case where one of the component is 0 (i. e. object comes down to zero speed to rest), then the total momentum of the flock of identical birds is zero when they are very tired and coming down to rest.
