Task: Answer the multiple choice question.
Question: Which compound exhibits a -4.501\% 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, or d without using any other words.
Options:
a.) CC(=O)c1sc(NC(=O)COc2ccc(Cl)cc2C)nc1C
b.) CC(C)CN(CC(C)C)C(=O)C12CCC(C)(C(=O)C1)C2(C)C
c.) S=c1[nH]nc(-c2ccco2)n1/N=C/c1ccc(Br)s1
d.) Cc1cc(CSc2nc(C)cc(=O)[nH]2)c2ncccc2c1
Answer: c. S=c1[nH]nc(-c2ccco2)n1/N=C/c1ccc(Br)s1
