Drilles are channels or grooves carved into the surface by flowing lava. They are a clear indicator of past volcanic activity, specifically associated with mare formation on the Moon. The other options are not necessarily indicative of volcanic activity. Rays around the latest eruptions could also be caused by impact events. Craters can be formed by impacts or other geological processes. Vents seen erupting in the mountainous highlands have not been observed on the Moon. The Orientale Basin is a large impact crater and not specifically related to volcanic activity. Drilles associated with lava flows accompanying the mare formation are the best evidence of lunar volcanism, as they are the result of volcanic activity that occurred during the formation of the lunar mare. Radiating rays and the Orientale Basin are also associated with lunar volcanism, but they are not the best evidence as they are the result of impact events rather than volcanic activity. Craters all over the Moon are also not a good indicator of lunar volcanism as they are the result of the Moon's history of being bombarded by objects in space. Vents seen erupting in the mountainous highlands are not a common feature on the Moon and are not a reliable indicator of lunar volcanism.
