Task: Answer the multiple-choice question.
Question: Which drug exhibits a 5.531\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a. O=C(Nc1nnc(S(=O)(=O)N2CCCCC2)s1)c1cccc(Br)c1
b. CCOc1cc(/C=C2/C(=N)N3C(=NC2=O)SN=C3S(=O)(=O)CC)ccc1OC(=O)c1ccco1
c. Nc1c(-c2ccccc2)cnn1-c1cccc([N+](=O)[O-])c1
Answer: a. O=C(Nc1nnc(S(=O)(=O)N2CCCCC2)s1)c1cccc(Br)c1
