Explanation
Even implies that the word is stronger than austere, though similar to that word. The word names something in Bourbaki’s proof that daunts or intimidates. You might anticipate something like “great difficulty.” Asperity means “severity,” which will work (it especially suggests a rough or harsh surface).
Rigor is an even closer synonym to “austerity.”
Hence options asperity, rigor are correct!
