(a) Option (B)
Alternative A has highest Present Worth, so this alternative is most economical.
(b) Discounted Payback Period (DPBP) is the year when the project's cumulative discounted cash flow is zero.
Net Cash Flow (NCF) ($) = Annual revenue - Annual cost
NCF, Alternative A = 79,397 - 17,368 = 62,029
NCF, Alternative B = 48,665 - 10,941 = 37,724
NCF, Alternative C = 96,112 - 22,944 = 73,168

If DPBP is between two successive years (N - 1) & N,
DPBP = (N - 1) + [Absolute value of cumulative discounted NCF in year (N - 1) / Discounted NCF in year N]
DPBP of Alternative A lies between year 6 and 7. DPBP of Alternative B lies between year 5 and 6. DPBP of Alternative C lies between year 8 and 9.
DPBP, Alternative A = 6 + (11,193 / 29,293) = 6 + 0.38 = 6.38 ~ 6 years
DPBP, Alternative B = 5 + (4,013 / 19,112) = 5 + 0.21 = 5.21 ~ 5 years
DPBP, Alternative C = 8 + (2,998 / 28,357) = 8 + 0.11 = 8.11 ~ 8 years
(ii) Option (D)
Alternative B has minimum DPBP, so this alternative preferred.
(c) Option (A)
The Payback period ignores cash flows after cut-off period and after the actual payback period, so its evaluation is different from that of PW method.
