Task: Answer the multiple-choice question.
Question: Which drug exhibits a -12.821% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a: COc1ccc(C2CC2C(C)=O)cc1
b: O=C(O)C[C@H]1c2cc(F)ccc2S(=O)(=O)N1C1CCCCC1
c: C=CCn1c(SCc2ccc(C(=O)NCCO)cc2)nc2ccccc2c1=O
d: Cc1cccc(OCc2n[nH]c(=S)n2C2CCCCC2)c1
Answer: c. C=CCn1c(SCc2ccc(C(=O)NCCO)cc2)nc2ccccc2c1=O
