Task: Answer the multiple choice question.
Query: Which drug exhibits a 21.802\% human ether-à-go-go related gene (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) COC(=O)CSc1nc(C)c(C(=O)Nc2ccccc2C)c(-c2ccc(Cl)cc2)c1C#N
(b) Cc1ccc(NC(=S)Nc2ccc(F)cc2)cc1
(c) COc1ccc(-c2c(C(=O)O)c(-c3ccccc3)cn2C)cc1
Answer: c. COc1ccc(-c2c(C(=O)O)c(-c3ccccc3)cn2C)cc1
