Option 1 states that in the winter season, isotherms in the Northern Hemisphere are more or less circular on continents. This means that in the winter, the lines on a map that connect areas with the same temperature tend to form circular patterns on land masses. This is because land is subject to more variations in temperature compared to the ocean.

Option 2 states that isotherms are parallel to latitude in the Southern Hemisphere in oceans. Isotherms in the Southern Hemisphere, specifically in the oceans, are found to be parallel to lines of latitude. This means that areas at the same latitude tend to have the same temperature.

Option 3 states that the minimum temperature during winter is recorded in Northern Canada. This means that Northern Canada experiences the lowest temperatures during the winter season compared to other regions.

The correct answer is option 1, as both statement 1 and statement 2 are correct. Option 3 is not correct as it states that Northern Canada has the lowest winter temperatures, which is not mentioned in the statements.
