A dam is to be constructed to provide a storage reservoir for a flood control project. The table below has descriptions of costs and benefits for five reservoir capacity options:

Reservoir capacity (acre-feet)	Initial construction costs ($ million)	Average annual O&M cost ($ million)	Average annual benefits ($ million)
50,000	4.5	0.032	0.317
100,000	5.0	0.079	0.761
150,000	8.0	0.127	1.078
200,000	14.0	0.143	1.269
250,000	22.0	0.190	1.332

Assume the project life = 50 years and i = 6%. Determine the reservoir capacity which:

1. Maximizes value of net benefits
2. Maximizes the benefit/cost (B/C) ratio
3. Maximizes the incremental benefit/cost ratio (DB/DC)
