Task: Answer the multiple choice question.
Query: Which drug exhibits a 0.713\% 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(Nc1ncccn1)c1cccc(F)c1
b: CC(C)C(C(=O)Nc1sc2c(c1C#N)CCCCC2)N1C(=O)c2ccccc2C1=O
c: CCCCc1cc(=O)oc2cc(C)cc(OCC(=O)NCCN3CCOCC3)c12
d: CCOc1ccc2nc(NC(=O)CSc3nnnn3C3CCCCC3)sc2c1
Answer: a. O=C(Nc1ncccn1)c1cccc(F)c1
