Task: Answer the multiple choice question.
Query: Which drug exhibits a 17.943\% 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] O=C(Nc1cccnc1)c1sc(Nc2ccccc2F)nc1-c1ccccc1
[b] Cc1cc(C)n2nc(C(=O)OCC(=O)NNC(=O)c3ccccc3)nc2n1
[c] Cc1ccc(-c2c(C(=O)O)c3ccccc3[nH]c2=O)cc1
[d] O=C(COc1ccc([N+](=O)[O-])cc1)Nn1cnnc1
[e] COC(=O)Cc1ccc(NC(=S)NCCCO)cc1
Answer: a. O=C(Nc1cccnc1)c1sc(Nc2ccccc2F)nc1-c1ccccc1
