Task: Answer the multiple-choice question.
Query: Which drug exhibits a 20.389\% 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: Cl.O=C(O)c1ccc(Nc2ncnc3scc(-c4ccccc4)c23)cc1
b: Cc1ccccc1NC(=S)Nc1cccc([N+](=O)[O-])c1
c: COc1ccc(C(C)=O)cc1Cn1nc(C)c([N+](=O)[O-])c1C
d: CN(C)C(=O)N1CCC(C(=O)NCc2ccccc2)CC1
e: CCC(=NCCc1c[nH]c2ccccc12)c1c(O)n(-c2ccc(C)cc2)c(=O)[nH]c1=O
Answer: a. Cl.O=C(O)c1ccc(Nc2ncnc3scc(-c4ccccc4)c23)cc1
