Answer: (a) Argentina, Mexico, South Africa and Turkey
Argentina, Mexico, South Africa and Turkey are all G20 members. Every other group includes a non-member: Malaysia and New Zealand in (b), Iran and Vietnam in (c), and Singapore in (d).
- ✓ (a) The G20 comprises 19 countries including Argentina, Mexico, South Africa and Turkey, along with the European Union.

- ✗ (c) Brazil and Saudi Arabia are members, but Iran and Vietnam are not.
