(b) A person acts knowingly, or with knowledge, with respect to his conduct or to attendant circumstances when he is aware of the nature of his conduct or that those circumstances exist. A person acts knowingly, or with knowledge, with respect to a result of his conduct when he is aware that his conduct is practically certain to cause the result.

(c) A person acts recklessly, or is reckless, with respect to attendant circumstances or the result of his conduct when he acts in awareness of a substantial risk that the circumstances exist or that his conduct will cause the result and his disregard is unjustifiable and constitutes a gross deviation from the standard of care that a reasonable person would exercise in the situation.
