I got this question in an international level competition.

This interesting question is from Digital Integrated Circuits in portion Boolean Algebra and Minimization Techniques and Logic Gates of Digital Circuits

Answer 1

Correct choice is (d) All of the Mentioned

For explanation I would say: For CMOS devices, all the mentioned statements are applicable. The devices should not be inserted into circuits with the power on. All tools, test equipment and metal workbenches should be tied to earth ground. Also, the devices should be stored and shipped in antistatic tubes or conductive foam.
