a) the type of feedback is decided by the connections of feedback element at input and output nodes, here the feedback is due to the resistor arrangement of R1,R2,R3 and this arrangement is directly connected to the input node at Negative opamp terminal and the arrangement is connected through the load resistor to the output node, thus it is direct connection at input and indirect at output which resembles a shunt mixing as the feedback element is in shunt with the source provided at input, and the output resembles a current sampling as the feedback is in series with the load resistance, thus the feedback is an shunt series feedback.this is called current sampling, the basic amplifier is current amplifier.
b)
