Task: Answer the multiple-choice question.
Query: Which compound has a 2.774\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a: CCC(C)(C)NC(=O)C(c1ccccc1)N(Cc1cccs1)C(=O)Cn1nnc2ccccc21
b: Cc1ccc(C)c(NS(=O)(=O)c2ccc(OCC(=O)NCC3CCCO3)cc2)c1
c: O=C(C1CCCN(S(=O)(=O)c2ccc(Br)s2)C1)N1CCCCCC1
d: COc1cccc(CNC(=O)c2ccccc2C(=O)NC(C)(C)C(=O)NCc2cccc(OC)c2)c1
Answer: c. O=C(C1CCCN(S(=O)(=O)c2ccc(Br)s2)C1)N1CCCCCC1
