The connection between art and conservation science in this sculpture is primarily through the idea of repurposing materials to create art. By using discarded water bottles to make an elephant sculpture, the artist highlights environmental issues such as plastic waste and encourages viewers to think about sustainability and conservation. This approach not only creates a compelling piece of art but also raises awareness about the importance of reusing materials and caring for the environment. Therefore, the correct response is:
The artist was repurposing materials to create art.
