$(1$ point$)$

In the circuit below, R$1=92\backslash$Omega $,$R$2=175\backslash$Omega $,$R$3=150\backslash$Omega $,$R$4=14\backslash$Omega $.$ An ohmmeter is an instrument that gives a value for the resistance seen between two terminals. What is the correct reading if the instrument is attached to the network in the figure given at points: $($a$)$ AD

$($b$)$ BD

$($c$)$ CD $?$

$($a$)$ R$\_($AD$)=\backslash$Omega

$($b$)$ R$\_($BD$)=\backslash$Omega

$($c$)$ R$\_($CD$)=\backslash$Omega
