Task: Answer the multiple choice question.
Query: Which drug has a 17.490\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
(a) CCC1=Nc2cc(C(=O)O)ccc2Sc2ccc(Cl)cc21
(b) COCCCNC(=O)c1ccc2c(c1)CCN2S(C)(=O)=O
(c) Cc1ccc(N2CC(C)Cn3c2nc2c3c(=O)n(CC(=O)OCc3ccccc3)c(=O)n2C)cc1C
(d) Cc1ccc(NC(=O)CSc2ncc(S(=O)(=O)c3ccccc3)c(=O)[nH]2)cc1C
Answer: a. CCC1=Nc2cc(C(=O)O)ccc2Sc2ccc(Cl)cc21
