Final answer:
If you were at your home at latitude 34º N, you would look for Polaris, the North Star, at an altitude of 34º above your northern horizon.
Step-by-step explanation:
If you were at your home at latitude 34º N, you would look for Polaris, also known as the North Star, at an altitude of 34º above your northern horizon (option c). This means that Polaris would be 34º above the point on the horizon where north is located. The altitude of Polaris above the horizon is equal to the observer's latitude, so at 34º N, Polaris would be 34º above the northern horizon.
