Answer:

The total energy is 4722 kJ/mol. (first option)

Step-by-step explanation:

1st) It is necessary to calculate the net energy of each group of bonds, the result is shown in the following table:

2nd) We have to add all the net energies for the reactants:

2065+347+358+467+495+495+495= 4722 kJ/mol

Finally, the total energy is 4722 kJ/mol.
