Which one of the following is a filter feeder

Explanation

Filter feeders are a subdivision of suspension-feeding entities which feed by straining suspended matter and food particles from water, by passing the water over a specialized filtering structure. Some animals that use this method of feeding are clams, krill, sponges, oysters, baleen whales, and many fish (including some sharks). Some birds, such as flamingos and certain species of duck, are also filter feeders.
