The answer is c. velocity
Based on your question the answer to this is the following and i hope i answered you question correctly:

Answer with Explanation:
Electric field:It is the force per unit charge experienced by rest charge at any given point.
It is the area around the charge which is placed at rest.It is represented by E.
Mathematical formula:

Magnetic field:It is an area around moving charge in which moving charge particle experienced magnetic force in that area.
Magnetic field is represented by B.
Mathematical formula :

Where B=Magnetic field
q=Charge on particle
v=Velocity of particle
F=Magnetic force exert on particle
Answer:
28.57 Mpc
Explanation:
This question is going to be solved by applying Hubble's Law.
This Hubble's Law is actually an observation in physical cosmology. This observation makes it clear that galaxies are moving away from the Earth, and are doing so at speeds proportional to their distance. This essentially means that the farther they are from the Earth, the faster they are moving away from Earth.
It is represented by this formula
v = H(0)D, where
v = speed
H(0) = Constant of proportionality, or otherwise, Hubble's constant.
D = Distance to a galaxy
Applying the given parameters to the formula, we have
v = H(0).D
D = v / H(0)
D = 2000 / 70
D = 28.57 Mpc
