Task: Answer the multiple-choice question.
Query: Which drug exhibits a 10.514\% 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(N/N=C/c1cccnc1)c1cccc(S(=O)(=O)Nc2cccc(Cl)c2)c1
b CCOC(=O)c1cc(-c2ccccc2)sc1NC(=O)c1cc(OC)c(OC)c(OC)c1
c O=C(CN1CCN(C(=O)c2ccco2)CC1)Nc1ccc(Br)cc1
d CCCCN(Cc1ccccc1)C(=O)c1cnc2n(c1=O)CCS2
e O=C(Nc1cc(C(=O)N2CCCC2)ccc1N1CCCC1)c1ccccc1F
Answer: c. O=C(CN1CCN(C(=O)c2ccco2)CC1)Nc1ccc(Br)cc1
