Task: Answer the multiple-choice question.
Question: Which drug exhibits a -11.885\% 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) O=C(COC(=O)c1ccc(OC(F)(F)F)cc1)NCCN1C(=O)CSC1=O
(b) CC1=NN(c2ccc([N+](=O)[O-])cc2)C(c2ccccc2)C1
(c) Cc1ccc(C(=O)NN2CCOCC2)cc1[N+](=O)[O-]
(d) CCN(CC)S(=O)(=O)c1ccc(N2CCOCC2)c(NC(=O)c2ccc3ccccc3c2)c1
Answer: a. O=C(COC(=O)c1ccc(OC(F)(F)F)cc1)NCCN1C(=O)CSC1=O
