Before being liberated by Rama from her curse, Ahalya was in which form ?

Ahalya was cursed by her husband Gautama Rishi to become a stone after being accused of infidelity with Indra. She remained in stone form until Rama's touch liberated her from the curse. In some versions, she was transformed into an invisible or withered form, but the stone transformation is the most well-known version in popular retellings of the Ramayana.
