Answer:
The correct answer is option A, A Magnetar
Step-by-step explanation:
The magnetic field strength of the given options in the question are as follows:
Magnetar - 1,000,000,000,000,000 Gauss
Jupiter - 1000 Gauss
our Sun - 1-5 Gauss
a supernova - 1013 Gauss
Magnetars are formed from the supernova and are known as neutron stars. It is the dynamo mechanism which plays an important role in the magnification of magnetic field of neutron stars by a factor of several thousand.
