Task: Answer the multiple choice question.
Query: Which drug has a 1.669\% 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) COc1ccc(CNC(=O)CSc2nnc(-c3ccc(NC(C)=O)cc3)n2C)cc1
(b) CCC(C)NC(=O)C1CCN(C(=O)COc2ccc3c4c(c(=O)oc3c2C)CCCC4)CC1
(c) CCc1c(C)c(C#N)c2nc3ccccc3n2c1NCc1ccccn1
(d) COC(=O)c1cccc(NC(=O)CCc2c(C)noc2C)c1
Answer: a. COc1ccc(CNC(=O)CSc2nnc(-c3ccc(NC(C)=O)cc3)n2C)cc1
