Object A $\left(m_{A}=1.0 \mathrm{~kg}\right)$ Hangs at Rest from an Ideal String $A$

Object A $\left(m_{A}=1.0 \mathrm{~kg}\right)$ hangs at rest from an ideal string $A$ connected to the ceiling. Object $B\left(m_{B}=2.0 \mathrm{~kg}\right)$ hangs at rest from an ideal string $B$ connected to object $A$ . The tension on string $A$ is

A) Twice the tension on string $B$
B) 1.5 times the tension on string $B$
C) Equal to the tension on string $B$
D) $\frac{2}{3}$ the tension on string $B$
E) Other (specify)
