To measure the population of lake trout in a 250-hectare lake, 500 individual trout were captured using nets and marked with a fin clip, then returned to the lake. The next week, the trout capture was repeated, and out of the 200 lake trout that were caught, 50 had fin clips. Using the mark-recapture estimate, the lake trout population size is predicted to be closest to which of the following?

A) 200
B) 400
C) 1,600
D) 2,000
