Two design options of a parallel system. The first parallel system is tited, Design Option B$.$ It

shows two components, $0\mathrm{.}9$ and $0\mathrm{.}95,$ connected in series at the top and two components,

$0\mathrm{.}9$ and $0\mathrm{.}95,$ connected in series at the bottom. The second parallel system is titled, Des$/$ign

Option C$.$ It shows two parallel systems connected in series. The first parallel system

comprises two identical components, $0.$s$.$ The second parallel system comprises two Identical

components, $0\mathrm{.}95.$

Find the rellability of the oribinal desion.

Explain how the conficurations of the proposed deations dififer.

Whith proposed desten hass the best rellabilliby?
