Final answer:
North is to your left when you are facing south.
Thus (option 3) is right answer.
This relates to the ancient Norse meaning of 'north' and is based on directional observations when facing the Sun's position at noon in the Northern Hemisphere.
Step-by-step explanation:
The ancient Norse word for 'left' is the root for the English word 'north'. This directional term dates back to a time when navigation and the understanding of our planet were significantly different than they are today. Thus (option 3) is right answer.
If you are facing the direction where the Sun rises, which is east, then north would indeed be to your left. Conversely, when you face west, where the Sun sets, north would also be to your left. However, the correct answer to the question is that north is to your left when you are facing south.
This is because as observed historically, the Sun is furthest from the horizon at noon in the south for those in the Northern Hemisphere. Hence, when facing south during midday, your shadow points north, and north is to your left.
