Which graph below has an Euler Circuit ?

Answers

The graph from the image attached that has an Euler Circuit is option d.

Note that Euler circuit path must have at least  2 odd Numbers and the others can be even numbers. From the above image (Option d), we can see that the Vertices have

  • A = 3
  • B = 3
  • C = 2
  • D = 4
  • E = 2

What is a Euler circuit?

An Euler circuit is known to be a kind of circuit that moves over all the edges at once and is said to often takes place once and begins and ends its process in the same place/point.

From the above, we can see 2 odd numbers (3) and the rest are even. So therefore, option d is correct.
