For the parametric equations x = 2 + 3cos t and y = -1 + 4sin t, which statement is correct?
A
They trace an ellipse centered at (2, -1) with horizontal major axis, foci (2 + sqrt(7), -1) and (2 - sqrt(7), -1), and eccentricity sqrt(7)/3.
B
They trace an ellipse centered at (2, -1) with vertical major axis, foci (2, -1 + sqrt(7)) and (2, -1 - sqrt(7)), and eccentricity sqrt(7)/4.
C
They trace a circle centered at (2, -1) with radius 4 and eccentricity 0.
D
