Task: Answer the MCQ question.
Question: Which compound exhibits a -4.471% human ether-à-go-go related gene (hERG) inhibition at 10uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a: CCSc1nnc(NC(=O)c2cc3c(s2)CCCC3)s1
b: Cc1ccc(C2C(C#N)=C(N)SC(N)=C2C#N)o1
c: CCOc1ccc(C(=O)Nc2ccc(N3CCCC3)cc2)cc1
Answer: b. Cc1ccc(C2C(C#N)=C(N)SC(N)=C2C#N)o1
