Task: Answer the multiple choice question.
Query: Which drug has a 17.940\% human ether-à-go-go related gene (hERG) inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.
Options:
a: O=C(COc1ccccc1[N+](=O)[O-])N(C1CCCCC1)C1CCS(=O)(=O)C1
b: COc1cccc(NC(=O)C2CSC3(C)CCC(=O)N23)c1
c: CCOC(=O)N1CCC(NC(=O)C2CCCN(C(=O)N3CCOc4ccccc43)C2)CC1
d: Oc1c(/C=C/C=C/C=Nc2ccccc2)sc(=S)n1Cc1ccccc1
e: c1cn(-c2ccc(-c3ccnc4ncnn34)cc2)cn1
Answer: a. O=C(COc1ccccc1[N+](=O)[O-])N(C1CCCCC1)C1CCS(=O)(=O)C1
