Task: Answer the multiple-choice question.
Query: Which drug exhibits a 11.390\% 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 additional words.
Options:
a: O=C(/C=C/c1ccccc1Cl)Nn1cnc2ccccc2c1=O
b: CCCNC(=O)C1CC(=O)N(c2ccc(OCC(=O)Nc3cccc(C)c3C)cc2)C1
c: CC(OC(=O)c1oc2ccccc2c1COc1ccccc1)C(=O)NC(N)=O
d: O=C(CSC1c2ccccc2-c2ccccc21)N/N=C/c1ccccc1
Answer: a. O=C(/C=C/c1ccccc1Cl)Nn1cnc2ccccc2c1=O
