For all $$z \in C$$ on the curve $$C_1$$: $$|z| = 4$$, let the locus of the point $$z + \dfrac{1}{z}$$ be the curve $$C_2$$. Then

A

the curves $$C_1$$ and $$C_2$$ intersect at 4 points

B

the curves $$C_1$$ lies inside $$C_2$$

C

the curves $$C_1$$ and $$C_2$$ intersect at 2 points

D

the curves $$C_2$$ lies inside $$C_1$$
