Answer 1

Correct choice is (d) Shell is a multi-faceted, command interpreter and provides an environment to work in

The explanation is: Shell is the agency that sits between the user and the UNIX system. It is a unique and multi-faceted program. It is also called command-interpreter because it interprets our command entered. It is also a programming language. From another point of view, the shell also provides us with an environment to work in.
