Which of the following is/are correct inference/inferences from isothermal maps in the month of January?

1. The isotherms deviate to the north over the continent.
2. The presence of cold ocean currents, Gulf Stream and North Atlantic Ocean colder and the isotherms bend toward the north.

Select the answer using the code given below:

(a) 1 only

(b) 2 only

(c) Both 1 and 2

(d) Neither 1 or 2

Correct Answer: 1 only

Explanation:
The isotherms deviate to the north over the continent during January due to the presence of warmer land temperatures compared to the surrounding oceans. The second statement is incorrect because the Gulf Stream and North Atlantic Drift make the adjacent areas warmer, not colder.
