The third base can establish $H$-bonds even with a non-complementary anticodon.

Vedclass · Answer

(B) According to the Wobble hypothesis proposed by Francis Crick,the pairing between the third base of the codon and the first base of the anticodon is less strict than the first two positions. This allows the third base of the codon to establish $H$-bonds even with a non-complementary anticodon,which explains the phenomenon of degeneracy in the genetic code.
