Option b:A nuclear equation is said to be balanced if the sum of the mass of A number and the sum of the atomic number Z is equal on both sides of the reaction arrow.In the nuclear reaction, atoms are represented as follows:Here, a represents the mass number, Z represents the atomic number and X represents the atomic symbol.a. The nuclear reaction is the following:Here, the sum of the mass number and atomic number on the left side of the reaction arrow is 23 and 11, respectively.On the right side of the sum of the mass number is 24+1=25 and the atomic number is 12+1=13. Since, both the mass number and atomic number are not the same, there is a balance of the nuclear reaction.b. The nuclear reaction is the following:Here, the sum of the mass number and atomic number on the left side of the reaction arrow is 24 and 11 respectively.On the right side of the sum of the mass number is 24+0=24 and the atomic number is 12-1=11. Since, both the mass number and atomic number are the same, this is a balance of the nuclear reaction.c. The nuclear reaction is the following:Here, the sum of the mass number and atomic number on the left side of the reaction arrow is 24 and 13 years, respectively.On the right side of the sum of the mass number is 24+0=24 and the atomic number is 12-1=11. Since then, the atomic number is not the same, there is a balance of the nuclear reaction.d. The nuclear reaction is the following:Here, the sum of the mass number and atomic number on the left side of the reaction arrow is 23 and 12, respectively.On the right side of the sum of the mass number is 24+1=25 and the atomic number is 12+0=12. Since then, the atomic number is not the same, there is a balance of the nuclear reaction.
