For pure iron it is the transition temperature (phase change temperature) between alpha iron and gamma iron. It is a thermal arrest temperature. So the question is confusing. The question itself should have some clarity.

Its depend on carbon content. If we look the iron-carbon phase diagram its true for 0.022% of carbon.

Iron Exists at 910°c alpha iron.
When Iron exists above 910°c then it is Gamma iron.
When Iron exists above 910°c then it is Gamma iron.

It mainly depends on carbon content. Though, based on the question it should be Gamma iron.

Alpha iron is stable upto 910 °C. But the more appropriate answer is γ iron.
