Summary
At night, a flock of crows will usually perch in a small place called a roost.
Every morning, the crows leave the roost to hunt and scavenge. Most flocks of crows keep their hunting to within 100 to 130 km from the roost.
Normally a flock of crows stays in the same roost for several years.
When a flock abandons a roost to form a new roost, the new roost is usually less than 8 km away from the abandoned roost.

There’s no clear inference from the stimulus. I’d rely on process of elimination to identify which answer can most justifiably be rejected.
