Answer 2

For the identification of each element, their appearance and working are to be considered.

Explanation:

Below are the noted characteristics of each of these elements which should be used for identification,

1. Diode - A diode is a two terminal device that conducts only in forward biased mode.
2. Transistor: A transistor is a three terminal device having an emitter, base and collector. So any three terminal devices in the mixture is a transistor.
3. Integrated Circuit (IC) - An integrated circuit is a multi terminal device and looks like a chip. So any multi terminal device in the mixture is an IC.
4. Resistor - A resistor is a two terminal device with a straight appearance and having rings in it. It conducts whenever a voltage is applied across it. There is no concept of biasing for a resistor  

Since both Diode and resistor are two terminal devices they both need to be identified either by their looks or by working principal i.e. resistor conducts for all the applied voltage while diode conducts only for forward biased voltage.
