Question

The circuit diagram below shows the locations of four switches. All four

switches are initially closed. Which switch must be opened in order to create
a complete (not short) circuit?

Answer 1

switch 2 must be opened Answer (C)

Step-by-step explanation:

If you leave switch 2 closed, there will be a short circuit because the current will go through the path of less resistance, therefore selecting the line where switch 2 is located, and avoiding all other branches where the resistors are placed.
