Who is the current governor of Indiana?

The current governor of Indiana is Eric Holcomb. He has been serving in this role since January 2017 after succeeding Mike Pence, who left the governorship to become vice president of the United States. As governor, Holcomb is responsible for overseeing the state government, implementing state laws, and managing the executive branch. His administration has focused on various issues, including education reform, infrastructure improvements, and economic development.

In contrast, Mike Pence had previously held the position of governor, but he is no longer in office. Joe Donnelly, while he served as a U.S. Senator, has never held the position of governor in Indiana. Tim Murphy does not hold any relevant political position in Indiana's current government structure. Thus, Eric Holcomb is the only correct answer regarding who is currently serving as governor.
