3. Isthmus of Munoz
4. Isthmus of Brunswick Peninsula

Answer 1

Correct Answer - Option 2 : Ofqui Isthmus

The correct answer is option 2, i.e, Ofqui Isthmus.

• Ofqui Isthmus connects the Chilean mainland with the Taitao Peninsula.
• The isthmus is bounded in:
  • in the south by the Gulf of Penas
  • in the north by the San Rafael Lagoon
  • in the west by the Taitao Peninsula
  • in the east by the Northern Patagonia Ice Field
• It lies close to the Chile Triple Junction where the Nazca Plate, the South American Plate  and the Antartic Plate meets.
• By draining a considerable amount of swampy isthmus, the San Tadeo River flows in South-Southwest direction into the Gulf of San Esteban.
