In the circuit shown in Fig. $$X$$ $$-$$ is an element which always absorbs power. During a particular operation, it sets up a current of $$1$$ $$amp$$ in the direction shown and absorbs a power $${P_{x}}.$$ It is possible that $$X$$ can absorb the same power $${P_x}$$ for another current $$i.$$ Then the value of this current is
A
$$\left( {3 - \sqrt {14} } \right)\,\,amps$$
B
$$\left( {3 + \sqrt {14} } \right)\,\,amps$$
C
$$5$$ $$amps$$
D
