Derick Dagger thought about murdering his wife, Glynda, so he could inherit her money. Over time he developed a plan that he kept in his filing cabinet. In furtherance of his plan, Dagger asked his lifelong friend, Patrick O'Leary, to assist him in murdering his wife. O'Leary declined to assist but lent his revolver to Derick for use in accomplishing the murder. O'Leary then demonstrated how to load and fire his gun, and Dagger and O'Leary agreed to divide the inheritance. Early that evening, while Glynda Dagger was preparing supper, Derick aimed the loaded gun at her through the kitchen window, but she kept moving, providing a poor target. He did not fire. In this situation, Dagger committed:
a. The crimes of solicitation, attempted murder, and conspiracy.
b. No crimes because the act of murder did not occur.
c. The crimes of solicitation and censpiracy only.
d. The crime of attempted murder only.
