Task: Answer the multiple choice question.
Query: Which drug exhibits a 6.696\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
[a] Cc1c(NC(=O)c2cccc(NC(=O)Cc3ccccc3F)c2)c(=O)n(-c2ccccc2)n1C
[b] CC1CN(c2ccc(Oc3ccccc3)cc2)c2nc3c(c(=O)n(CC(N)=O)c(=O)n3C)n2C1
[c] Cc1nn(-c2ccccc2)nc1-c1nnc(-c2ccc(C(F)(F)F)cc2)o1
[d] CC(NC(=O)c1ccc(Br)s1)c1ccncc1
[e] CCOC(=O)C(NC(C)=O)(Nc1ccc(S(=O)(=O)Nc2ncccn2)cc1)C(F)(F)F
