What was the meaning of the symbol Horse of Sambhavnath Tirthankar?

The correct answer is: B. Restrained heart.

The horse is a symbol of restrained heart because it is a powerful animal that can be easily controlled by its rider. This represents the ability of a Tirthankar to control their own mind and emotions, even in the face of difficult situations.

The other options are incorrect because:

• Speed is not the main characteristic of a horse.
• Anger is not a positive quality that a Tirthankar would want to represent.
• Charm is not a quality that is associated with horses.
