Task: Answer the multiple-choice question.
Question: Which drug exhibits a -0.204\% 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 other words.
Options:
a O=C(NCc1ccccc1)C(c1ccccn1)N(C(=O)c1csnn1)c1ccccc1F
b CCOC(=O)c1[nH]c2ccc(Cl)cc2c1-c1ccccc1
c CCOc1ccccc1/C=N/NC(=O)Cc1csc(Nc2cccc(C(F)(F)F)c2)n1
d Cc1ccc(S(=O)(=O)N(CC(=O)N(C)C)c2cccc([N+](=O)[O-])c2)cc1
e O=C(COC(=O)c1cnccn1)N=c1sccn1Cc1ccccc1Cl
Answer: a. O=C(NCc1ccccc1)C(c1ccccn1)N(C(=O)c1csnn1)c1ccccc1F
