Task: Answer the multiple-choice question.
Question: Which drug exhibits a 20.578% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
a Oc1ccc(N=Nc2ccc3c(c2)OCO3)c2ccccc12
b Cc1cccnc1NC(=O)C1CCN(S(=O)(=O)c2ccc3c(c2)CCC(=O)N3)CC1
c COc1ccc(Nc2nnc(SCC(=O)Nc3ccc4[nH]c(=O)[nH]c4c3)s2)cc1
d O=C(O)C1=C[C@H](c2ccc3c(c2)OCO3)C[C@H](OCc2ccc(CO)cc2)O1
e O=S(=O)(NCc1ccccc1)NCc1ccccc1F
Answer: d. O=C(O)C1=C[C@H](c2ccc3c(c2)OCO3)C[C@H](OCc2ccc(CO)cc2)O1
