Task: Answer the multiple-choice question.
Query: Which drug has a 18.015\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a: CCSc1nnc(NC(=O)CC)s1
b: O=c1[nH]c(=O)n([C@H]2C[C@H](O)[C@@H](CO)O2)cc1C(F)(F)F
c: COc1ccccc1/C=C/C=N\N1CCN(Cc2ccccc2Cl)CC1.Cl
Answer: b. O=c1[nH]c(=O)n([C@H]2C[C@H](O)[C@@H](CO)O2)cc1C(F)(F)F
