Problem statement: Answer the multiple choice question.
Query: Which drug has a 3.393\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
(a) CCOC(=O)C1=C(O)CSC1=Nc1ccc(C)cc1
(b) Cc1sc2ncn(CC(=O)NCCCOC(C)C)c(=O)c2c1S(=O)(=O)N1CCN(c2ncccn2)CC1
(c) C/C=C/c1ccc(OCC(=O)O)c(OC)c1
Answer: a. CCOC(=O)C1=C(O)CSC1=Nc1ccc(C)cc1
