This question appears to have a factual issue based on available public information. There is no formally constituted Telangana Education Commission with a designated chairperson widely reported in the news.
However, within the context of Telangana education reforms and committees, Prof. A. Murali is a prominent name. He is a retired IAS officer known for his work in education, particularly in the social welfare residential schools. It is possible the question is referring to a specific committee or role he has held.
Given the options, and recognizing that exam questions can sometimes be flawed or refer to specific, less-publicized bodies, if one must choose, A. Murali is the most plausible answer related to educational leadership in Telangana. The provided key confirms this choice.
