Options

  1. AAzores Islands
  2. BAscension Islands
  3. CHawaiian Islands
  4. DTristan da Cunha

Correct answer

C. Hawaiian Islands

Step-by-step solution

The Hawaiian Islands are formed by intraplate hotspot volcanism in the middle of the Pacific Plate, located far away from any plate boundaries. The Azores Islands, Ascension Islands, and Tristan da Cunha are all volcanic islands situated along the Mid-Atlantic Ridge, which is a divergent tectonic plate boundary. Therefore, the Hawaiian Islands are not associated with a mid-oceanic ridge.
