Task: Answer the multiple-choice question.
Question: Which drug exhibits a 12.773\% 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: C=CCNCCCCOc1ccc(Br)cc1C.O=C(O)C(=O)O
b: Br.O=C(NCCNCc1ccccn1)c1ccco1
c: O=c1[nH]c(=S)n(C2CC2)c(O)c1C=NCCc1ccccc1
Answer: b. Br.O=C(NCCNCc1ccccn1)c1ccco1
