In a typical instrumentation amplifier that uses 3 OPAMPs :

(ಹ) OPAMPs connected to the inputs are voltage followers and the OPAMP connected
to the output is a differential amplifier

(B) OPAMPs connected to the inputs are inverting amplifiers and the OPAMP
connected to the output is a summing amplifier

)0 OPAMPs connected to the inputs are voltage followers and the OPAMP connected
to the output is a summing amplifier

(D) OPAMPs connected to the inputs are non-inverting amplifiers and the OPAMP
connected to the output is a summing amplifier
