c$.$ MAFTech assembles smart devices part from four major components arranged as follows:

The components can be purchased from three different vendors, who have supplied the following reliability data.

$\backslash$table$[[,$Vendor$],[$Component$,1,2,3],[$A$,0\mathrm{.}94,0\mathrm{.}85,0\mathrm{.}92],[$B$,0\mathrm{.}86,0\mathrm{.}88,0\mathrm{.}90],[$C$,0\mathrm{.}90,0\mathrm{.}93,0\mathrm{.}95],[$D$,0\mathrm{.}93,0\mathrm{.}95,0\mathrm{.}90]]$

i$.$ If MAFTech has decided only to use one vendor to supply all four components, analyze for which vendor should be selected.

$($CO$2$: PO$2-4$ Marks$)$

ii$.$ Define the decision made, if all the components were assembled in series. $($sequence of A$-$B$-$C$-$D and not sub$-$process B feed to C as above$)$
