please complete the whole question. a-c and the chart

At a given location, the damage costs associated with events of various magnitudes (return periods) are given in Table 4, Column 4. Annualized capital costs of structures designed to control events of the same magnitudes are given in Column 7. a. Fill in table below to determine the expected annual damages should no structures be built or if structures are built to the given design level. b. Find the optimal design level. Complete one example calculation on engineering paper using standard engineering format as given in the Problem Solving template. Enter final answers the Table and answer the question(s) below. Table 4: Damage and capital costs associated with flood protections structures. c. In narrative (paragraph) form, compare the no-build option to the optimum design level indicated by this analysis. Compare expected annual damages, capital costs, and total costs of both options
