Task: Answer the multiple choice question.
Question: Which drug has a 8.777\% 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 additional words.
Options:
a Cc1ccc(S(=O)(=O)N2CCC[C@H]2C(=O)OCC(=O)c2ccc3c(c2)NC(=O)CO3)cc1
b CCC(C)c1ccc(OCc2ccc(C(=O)OC)o2)cc1
c C[C@@H](CN1C2=NC[C@H](Cc3ccccc3)N2C[C@H]1Cc1ccc(O)cc1)NC(=O)CCC1CCCCC1
d C=CCn1cc(Cl)c(=O)n(CC=C)c1=O
Answer: d. C=CCn1cc(Cl)c(=O)n(CC=C)c1=O
