Task: Answer the multiple choice question.
Query: Which drug has a -27.485% 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 other words.
Options:
a. CCOC(=O)c1ccc(NC(=O)N2CCN(S(C)(=O)=O)CC2)cc1
b. O=[N+]([O-])c1cccc(/C=C2\CCC(/C=N/Nc3ccc4ccccc4n3)=C2N2CCOCC2)c1
c. Cc1nc(NC(=O)c2ccc3c(c2)OCO3)ccc1Br
d. O=c1oc2ccccc2n1CCCOc1ccccc1
Answer: d. O=c1oc2ccccc2n1CCCOc1ccccc1
