Answer:

Explanation:
We know that impedance of a RLC circuit is given by 
So
here R is resistance
is inductive reactance and
is capacitive reactance
To minimize the impedance
should be zero we know that 
So 


We know that 
So 

Where f is resonance frequency
A 'velocity' is built out of a speed and a direction.
The only item on that list that has a speed and a direction is the <em>first one</em>. The speed is 30 m/s and the direction is south.
Answer:
the awnser to the question is Is C
