Answer to Question 1

e.
The Big Bang does explain that the universe used to be very dense and therefore very hot. The expansion of the universe explains the cooling

Answer to Question 2

d.
By the end of the first three minutes, the universe had cooled enough for the nuclear strong force to take effect and nucleons bound together to form deuterons.
