Task: Answer the multiple-choice question.
Question: Which drug exhibits a 9.843\% 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 COC(=O)c1c(NC(=O)c2ccco2)sc2c1CCC2
b N#Cc1c(NC(=O)CCN2C(=O)c3ccccc3C2=O)oc(-c2ccccc2)c1-c1ccccc1
c O=C1COc2ccc(-c3n[nH]c(=O)c4ccccc34)cc2N1
d CC(=O)Nc1ccc(S(=O)(=O)Nc2ccc3c(c2)OCCO3)cc1Cl
Answer: c. O=C1COc2ccc(-c3n[nH]c(=O)c4ccccc34)cc2N1
