When starting a turbine engine, a hung start is indicated if the engine

exhaust gas temperature exceeds specified limits
fails to reach idle rpm
N1 is normal, but N2 is low
fuel pressure is too high

The correct answer is: exhaust gas temperature exceeds specified limits

A "Hung start" occurs when an engine fails to accelerate to idle speed after the starter is disengaged. This can be caused by a variety of factors such as incorrect fuel-to-air ratio, incorrect timing, or inadequate airflow. In this scenario, the only option that directly relates to engine acceleration is the exhaust gas temperature exceeding specified limits. The other options, while they could indicate potential issues with the engine, do not directly relate to the engine's ability to reach idle rpm.
