Task: Answer the multiple choice question.
Question: Which drug exhibits a -6.848% 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. CCOC(=O)C1CCN(C(c2cccc(F)c2)c2sc3nc(C)nn3c2O)CC1
b. C=CCNS(=O)(=O)c1cc2c3c(c1)CCN3C(=O)CC2
c. O=C(COc1nncc2ccccc12)Nc1c(F)c(F)c(F)c(F)c1F
d. O=C(CCNC(=O)c1ccccc1)Oc1ccc([N+](=O)[O-])cc1
e. O=c1c(C/C=C/c2ccccc2)c(O)ccn1Cc1cccc(Cl)c1
Answer: a. CCOC(=O)C1CCN(C(c2cccc(F)c2)c2sc3nc(C)nn3c2O)CC1
