C Step 1: Determine the change in proton number after alpha emission. An alpha particle is _2^4He. When a nucleus emits an alpha particle, its proton number (atomic number, Z) decreases by 2. Initial proton number = 74. Proton number after alpha emission = 74 - 2 = 72. Step 2: Determine the change in proton number after beta emission. A beta particle (specifically, a beta-minus particle) is _-1^0e. When a nucleus emits a beta-minus particle, a neutron converts into a proton, and its proton number (atomic number, Z) increases by 1. Proton number after alpha emission = 72. Proton number after beta emission = 72 + 1 = 73. The final proton number of the product is 73. The final answer is C 73.
