In the context of Maharashtra, several cave sites are recognized for their historical and cultural importance, but not all are listed as UNESCO World Heritage Sites.

The Ajanta Caves are significant for their artistic and architectural achievements, showcasing the development of Buddhist art and culture over several centuries.
The Ellora Caves, also located in Aurangabad, are another UNESCO World Heritage Site. These caves are renowned for their elaborate rock-cut architecture and sculptures, representing a blend of Hindu, Buddhist, and Jain religious art. The Ellora Caves are particularly famous for the Kailasa Temple, which is a massive monolithic rock-cut temple dedicated to Lord Shiva.
The Elephanta Caves, located on Elephanta Island near Mumbai, are also a UNESCO World Heritage Site. These caves are known for their rock-cut stone temples and sculptures dedicated to Lord Shiva. The Elephanta Caves are significant for their intricate carvings and the grandeur of their architecture, which dates back to the 5th to 8th centuries CE.
However, the Kanheri Caves, located in the Sanjay Gandhi National Park in Mumbai, are not listed as a UNESCO World Heritage Site. These caves are significant for their historical and religious importance, as they were used as a Buddhist monastery and have several rock-cut caves with inscriptions and sculptures. Despite their historical significance, the Kanheri Caves have not received the UNESCO designation, making them the correct answer to the question.
