Task: Answer the multiple-choice question.
Query: Which drug has a 0.830\% 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=C1N=C(N2CCCC2)S/C1=C\c1ccccc1
b. Cc1cc(C(=O)N/N=C/c2cc(Br)cc([N+](=O)[O-])c2O)c2ccccc2n1
c. O=C(CN1CCOCC1)Nc1cccc(Br)c1
d. Cc1occc1C(=O)N1CCC2(CCCN(Cc3ccc(F)c(F)c3)C2)C1
e. COc1ccc(NC(=O)CN2CCc3ccccc3C2)c([N+](=O)[O-])c1
Answer: c. O=C(CN1CCOCC1)Nc1cccc(Br)c1
