Task: Answer the multiple choice question.
Question: Which drug has a 8.146\% 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)c1ccccc1NC(=O)CCn1c(=O)oc2ccccc21
b.) Cc1ccc(C(=O)OCC(=O)Nc2ccc3[nH]c(=O)[nH]c3c2)cc1[N+](=O)[O-]
c.) CCOC(=O)CNC(=S)N(Cc1ccco1)Cc1ccccc1Cl
d.) O=C1ON=C(c2ccccc2)/C1=C/c1ccc(OS(=O)(=O)c2ccccc2)cc1
