Option c is the correct answer. The wheel with deer is a symbol of the Buddha's first sermon, which is also known as the Dhammacakkappavattana Sutta. This sermon was given in Sarnath, after Buddha attained enlightenment. In the sermon, the Buddha laid out the Four Noble Truths and the Noble Eightfold Path, the central teachings of Buddhism. The deer are said to represent all beings, and the wheel represents the Dharma, or the Buddha's teachings. The combination of the deer and the wheel symbolizes the Buddha's message of compassion and understanding for all beings.
