The four alternatives described belove are being evaluated: The Incremental IRRs are: \[ \begin{array}{l} \text { IRR, }=7 \% \\ I R_{2}=20 \% \\ \text { IRR, }=1 \% \\ \text { IRR, }=14 \% \\ \text { IRR, }=10 \% \\ \text { IRR_ }=12 \% \end{array} \] If the altematives are mutually axclusive, which one(s) should be selected if MARR=9.5%/ year?
