Problem statement: Answer the multiple-choice question.
Query: Which drug has a 2.446% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
a: Cc1coc2c(C)c3oc(=O)c(CCC(=O)N4CCC(C(=O)NCCCC(=O)O)(c5ccccc5)CC4)c(C)c3cc12
b: C=CCSc1nc(N)c(C#N)c(-c2ccccc2)c1C#N
Answer: b. C=CCSc1nc(N)c(C#N)c(-c2ccccc2)c1C#N
