Pls answer

which of the following statements correctly describes a transformer?

a) transformers use steady magnetic fields to induce an end in a secondary loop
b) the more could in the solenoid of the primary loop of a transformer will induce a greater emf in the secondary loop.
c) transformers are used to keep the emf constant throughout a circuit.
d) the transformer in a car engine reduces the end in the secondary coil so as not to cause a fire during start up.

b) The more could in the solenoid of the primary loop of a transformer will induce a greater emf in the secondary loop.

Explanation:

I think what that option was saying was the closer to the magnet the solenoid is, the faster it is going and the greater is the magnetic field due to the magnet in the vicinity of the solenoid, so the emf increases.
