What is the most likely cause of this variation between Asian and African elephants?
OA. Multiple African elephants developed mutations in the cells of their trunk from prolonged exposure to direct sunlight,
causing the lobe duplication, and passed this mutation on to their offspring.
OB. An individual African elephant had an error occur during DNA replication that resulted in a trunk with a selective
advantage, and passed this mutation on to its offspring.
OC. Several African elephants all developed the same mutation at the same time, which caused them to use their trunk
more efficiently
OD. African elephants used their trunks for grasping more than Asian elephants did, so their DNA mutated and caused their
trunks to develop differently
