The big bang theory is one of the most accepted theories on the origin of the universe because of scientific evidence, such as

(a)cosmic microwave background radiation spread uniformly throughout the universe was found
(b)an early form of hydrogen was found
(c)left over heat from the explosion was found
(d)distant, exploding quasars were found

Correct answer choice is :

A) Cosmic microwave background radiation spread uniformly throughout the universe was found

Explanation:

The Big Bang is a scientific theory about how the universe began, and then got the stars and galaxies we see today. The universe started as a very hot, small, and compact super force with no stars, atoms, form, or structure. Scientists also have discovered cosmic microwaves background radiation. This radiation is identified as radio waves, and they are everywhere in the universe.

a.metals can become magnetic if they have many spinning electrons that create magnetic fields.d.only some metals are attracted by magnets; these metals are called ferromagnetic.

d.wrapping an insulated wire around a metal with ferromagnetic properties and applying an electric current.
