At which location would and observer on the earth have the best chance of seeing a total solar eclipse

The correct answer is 2. An observer on the Earth would have the best chance of seeing a total solar eclipse from location B.

Explanation:

There are three types of solar eclipse:

-Partial: The Moon does not cover the solar disk completely, appearing a bright half moon.

-Total: From a strip on the surface of the Earth, the Moon completely covers the Sun. Outside the band of totality the eclipse is partial. A total eclipse will be seen for the observers located in the Earth that are within the cone of moon shadow, whose maximum diameter on the surface of our planet will not exceed 270 km, and which moves in an easterly direction at about 3200 km / h .

-Annular: Occurs when the Moon is near apogee and its angular diameter is smaller than the solar, so that in the maximum phase a ring of the Sun's disk remains visible. This happens in the annularity band; outside of it the eclipse is partial.
