Task: Answer the multiple choice question.
Question: Which drug exhibits a 7.777\% 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. S=C1NC(c2cccs2)=CC(c2ccc(Br)cc2)N1
b. CCN(CC)S(=O)(=O)c1ccc(NC(=O)[C@@H](NC(=O)c2cc(OC)cc(OC)c2)C(C)C)cc1
c. CC(Oc1ccccc1C(N)=O)C(=O)Nc1ccc(S(=O)(=O)N2CCCC2)cc1
d. O=C(/C=C/c1ccco1)OCC(=O)c1cccc([N+](=O)[O-])c1
e. CN(C)c1ccc(P(=O)(COc2ccc([N+](=O)[O-])cc2)c2ccc(N(C)C)cc2)cc1
Answer: a. S=C1NC(c2cccs2)=CC(c2ccc(Br)cc2)N1
