The correct answer is "เพราะโลกเอียงขั้วใต้เข้าหาดวงอาทิตย์". This is because the Earth's axis is tilted towards the Sun during the summer season in the Northern Hemisphere, causing it to receive more direct sunlight and resulting in warmer temperatures. Conversely, during the winter season in the Southern Hemisphere, the Earth's axis is tilted away from the Sun, causing it to receive less direct sunlight and resulting in colder temperatures.

The observer in Thailand is located at a latitude of 60o north, which means they are in the northern hemisphere. The observer in Thailand sees Mars at an azimuth angle of 90o and an altitude angle of 45o. Since the observer is in the northern hemisphere and the altitude angle is positive, this means that Mars is located in the northern part of the sky. Therefore, the correct answer is "ด้านตะวันตกเฉีนงเหนือ" which translates to "northwest".
