Task: Answer the MCQ question.
Query: Which drug exhibits a -21.175% human ether-à-go-go related gene (hERG) inhibition at 10uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
[a] C/C(N)=C(/C#N)C(=O)CSc1nc2ccccc2c(=O)n1CCCOC(C)C
[b] Cc1c(S(=O)(=O)N2CCN(c3ccc(F)cc3)CC2)c(=O)n(C)c(=O)n1C
Answer: a. C/C(N)=C(/C#N)C(=O)CSc1nc2ccccc2c(=O)n1CCCOC(C)C
