The correct answer is: A. Vijaya.
Ajitnath Tirthankara was born from the womb of Vijaya, the daughter of King Shanti and Queen Padmavati. Vijaya was a pious and virtuous woman who had performed many good deeds in her previous lives. As a result, she was reborn as the mother of Ajitnath, the 11th Tirthankara of Jainism.
Vijaya was a loving and caring mother who raised Ajitnath with great devotion. She taught him the importance of compassion, non-violence, and truthfulness. Ajitnath grew up to be a wise and compassionate man who dedicated his life to helping others. He became a Tirthankara, or a spiritual teacher, and helped many people to achieve enlightenment.
The other options are incorrect because they are not the names of the mothers of Ajitnath Tirthankara. B. Tara was the mother of Parshvanatha, the 23rd Tirthankara of Jainism. C. Sharmestha was the mother of Mahavira, the 24th and final Tirthankara of Jainism. D. Geeta was a character in the Hindu epic Mahabharata.
