Task: Answer the multiple-choice question.
Query: Which drug exhibits a 19.600\% 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(Nc1ccc(S(=O)(=O)Nc2ccccn2)cc1)c1cccc(Br)c1
b: O=C(CC(=O)Nc1ccccc1F)Nc1ccccc1F
c: O=C(NCc1cccnc1)c1ccc(NC(=O)c2ccc(Br)cc2)cc1
d: COc1cc(/C=C2/C(=O)N(c3cccc(Br)c3)N=C2C)cc(OC)c1O
e: CC(C)CCCN1C(N(C)C)=NC[C@@H]1Cc1ccccc1
Answer: c. O=C(NCc1cccnc1)c1ccc(NC(=O)c2ccc(Br)cc2)cc1
