Answer to Question 1

D

Answer to Question 2

Deuterium is created in stellar cores now, but just as quickly consumed in the making of helium on the main sequence. So any free deuterium must be left over from primordial nucleosynthesis; its survival means that the matter density could not have been anywhere near critical.
