Task: Answer the MCQ question.
Question: Which drug has a 6.336\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a) CCCCN1C(C)=CC(=C2C(=O)c3ccccc3C2=O)C=C1C
b) Cc1ccc(CNC(=O)CCCn2nc(C)n3ccnc3c2=O)cc1
c) Nc1cc(=O)[nH]c(SCC(=O)Nc2ccc(F)c(Cl)c2)n1
Answer: a. CCCCN1C(C)=CC(=C2C(=O)c3ccccc3C2=O)C=C1C
