Task: Answer the multiple choice question.
Question: Which drug exhibits a 12.934\% 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 O=C(CC(C(=O)O)c1cccc(Cl)c1)c1ccccc1
b O=C(c1cc([N+](=O)[O-])ccc1N1CCOCC1)N1CCCCC1
c COc1cccc(/C=C2\SC(=S)N(CCC(=O)Nc3ccc(O)cc3)C2=O)c1
d O=C(Nc1ncc2c(n1)-c1ccccc1OC2)c1ccc(Cl)cc1Cl
Answer: a. O=C(CC(C(=O)O)c1cccc(Cl)c1)c1ccccc1
