Task: Answer the multiple-choice question.
Query: Which drug exhibits a -2.742\% 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. CCOC(=O)c1c(C)nc2ccccc2c1-c1ccccc1.Cl
b. COc1ccccc1CNC(=O)COC(=O)C1CCN(S(=O)(=O)c2ccccc2)CC1
c. O=C(O)c1cccc(NC(=S)NC(=O)C(c2ccccc2)c2ccccc2)c1
d. CCC(C)NCCCOc1ccc([N+](=O)[O-])cc1.O=C(O)C(=O)O
Answer: a. CCOC(=O)c1c(C)nc2ccccc2c1-c1ccccc1.Cl
