Explanation:

Spawning is the reproductive process. By spawning, salmon produce many eggs. Even though adults die, the large number of eggs increases the likelihood that some offspring will survive (due to factors like predation, environmental conditions etc.). This ensures the continuation of the species. Option A is incorrect as spawning is about reproduction not population control of adults. Option C just states a fact about spawning behavior adaptation but doesn't explain the benefit. Option D is not the main benefit as the key is about offspring survival for species continuation.

Answer:

B. Spawning increases the chances that more offspring will survive.
