To determine which city is most likely to experience a major earthquake based on the locations of lithospheric plates, we need to consider their proximity to tectonic plate boundaries.
- **Paris (A)** is located in a relatively stable part of the Eurasian Plate, away from major tectonic boundaries.
- **New York (B)** is also situated on the stable North American Plate, although there are some minor fault lines nearby.
- **Rio de Janeiro (C)** is near the boundary between the South American Plate and the Nazca Plate, making it more susceptible to seismic activity.
- **Juneau (D)** is located in Alaska, which is close to the Pacific Plate boundary and has a history of significant seismic activity.
Based on this information, **Juneau (D)** is most likely to experience a major earthquake due to its proximity to tectonic plate boundaries known for high seismic activity.
