Task: Answer the multiple choice question.
Query: Which drug exhibits a -6.670% human ether-à-go-go related gene (hERG) inhibition at 10uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
[a] N#C/C(=C/c1ccc(Sc2nc3ccccc3[nH]2)o1)c1ccccc1F
[b] c1ccc2c(c1)[nH]c1ccncc12
[c] O=C(O)/C=C/c1cccc(NC(=O)c2ccc(Cl)cc2)c1
Answer: b. c1ccc2c(c1)[nH]c1ccncc12
