Explanation / Answer
The new nucleus has 1 unit less in Z ( new nucleus has 1 proton less.). One electron is involved in reaction. Atomic masses must be unchanged. Answer b Answer a No answer is correct. Before 24092U must be 24494X. This nucleus is not in list. answer a answer b .you have two new nuclei. answer a
