On the first swing, a pendulum swings through an arc of length 65 cm. On the successive swing, the length of the arc is 85% of the length of the previous swing. Write a rule to model this situation.

A. A(n) = 0.85 · (0.65)n − 1
B. A(n) = 0.85 · (65)n − 1
C. A(n) = 65 · (0.85)n − 1
D. A(n) = 65 · (85)n − 1
