Problem statement: Answer the MCQ question.
Query: Which drug exhibits a 2.149% 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: COc1ccc(CCNC(=O)CSc2nn(-c3ccccc3)c(=S)s2)cc1
b: CCOc1ccccc1C1CC(=O)NC(SCC)=C1C#N
c: CC1CCN(C(=O)C2CCC(C)(C(=O)O)C2(C)C)CC1
Answer: b. CCOc1ccccc1C1CC(=O)NC(SCC)=C1C#N
