Ramoji Rao Failed to Accept Chiru Challenge Due to?

Having accepted NTV chief Narendra Chowdary's green challenge, Megastar Chiranjeevi, himself, planted three saplings in his house garden and released a video message. Furthermore, he threw out a challenge to Power Star Pawan Kalyan, media baron Ramoji Rao and Big B Amitabh Bachchan. 

Since Ramoji Rao exhibits lot of social responsibility, he was thought to have accepted Megastar's challenge immediately. However, nothing of that sort happened now. 

According to inside sources, old age ailments could have been hampered Ramoji in doing so. "He might not bend his body to plant a sapling. Chiranjeevi sir shouldn't have thrown such a tough challenge to him," opines a doctor from Ramoji Film City. On the other hand, Amitabh is busy working for films. Whenever he finds enough time, he is likely to accept Chiranjeevi's challenge.As we know, Amitabh played Chiranjeevi's guru in Sye Raa Narasimhareddy.
