Problem statement: Answer the multiple choice question.
Query: Which compound has a 1.830\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a: N#Cc1ncc(C(F)(F)F)cc1Oc1cccnc1
b: CC12CCC(=O)N1C(C(=O)N1CCN(S(=O)(=O)c3ccccc3F)CC1)CS2
c: O=C(Nc1ccc(F)cc1F)N1CCN(c2ncccn2)CC1
Answer: c. O=C(Nc1ccc(F)cc1F)N1CCN(c2ncccn2)CC1
