Task: Answer the multiple choice question.
Question: Which drug has a 2.308\% 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: CCOC(=O)c1cc(-c2ccccc2)sc1NC(=O)CSc1nnc(N)s1
b: O=C(Nc1ccnn1C1CCN(C(=O)c2ccc(F)c(Cl)c2)CC1)C1CC1
c: O=C(Nc1nccs1)c1ccc(Br)o1
d: CN(C)c1cc(NC(=O)CN2CCCC2)c2ccccc2n1.O=C(O)C(=O)O
e: COc1cc(Cl)cc(C2NC(=S)NC(c3ccccc3)=C2C(C)=O)c1OCC(=O)O
Answer: c. O=C(Nc1nccs1)c1ccc(Br)o1
