If the universe had expanded at its original rate beyond the time when the strong nuclear force became a distinct force (about 10-³⁵ s after the Big Bang),the isotropy problem would have arisen: Parts of the universe we see in opposite directions would never have been in equilibrium with each other and should not exhibit the degree of isotropy we observe.The proposed solution to this problem is:

The proposed solution to the isotropy problem is cosmic inflation, which suggests that the universe expanded exponentially for a short time immediately after the Big Bang, which allowed distant regions to come into equilibrium with each other and explain the observed isotropy. This mechanism was proposed to resolve several problems in cosmology, including the isotropy problem. Choices A, B, and D are not related to the isotropy problem.
