Problem statement: Answer the multiple-choice question.
Query: Which drug has a 0.589\% 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(Nc1nnc(-c2ccco2)s1)C1CCCCC1
b: O=c1[nH]cnc2scc(-c3ccsc3)c12
c: CCn1c(=O)c(C(=O)Nc2ccccc2)c(O)c2ccccc21
d: O=C(c1ccc(S(=O)(=O)c2ccccc2Cl)c([N+](=O)[O-])c1)N1CCN(Cc2ccccc2)CC1
e: Cc1ccccc1OCc1nnc(SCC(=O)Nc2ccc3nc(SCC(=O)NC(C)(C)C)sc3c2)n1C
Answer: a. O=C(Nc1nnc(-c2ccco2)s1)C1CCCCC1
