Question Analysis
This question tests the understanding of the tangent function and its values in different quadrants.

Key Concept Explanation
45° is an angle in the first quadrant.
The tangent function is positive in the first and third quadrants.

Step-by-step Solution
1. Identify the reference angle for 45° in the third quadrant: $$180^\circ + 45^\circ = 225^\circ$$
2. Verify that tan(225°) = tan(45°)
3. Therefore, the correct answ...
