Task: Answer the multiple-choice question.
Query: Which compound exhibits a -5.441% 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] CCc1cc(=O)oc2cc(OS(C)(=O)=O)ccc12
[b] Cc1ccc(NC(=O)/C(C#N)=C/c2cc(C)n(-c3ccc(N4CCOCC4)c([N+](=O)[O-])c3)c2C)c(C)c1
[c] CC(C)c1cc(-c2cc(C(=O)Nc3ccccc3)on2)nc(NC2CCCC2)n1
Answer: a. CCc1cc(=O)oc2cc(OS(C)(=O)=O)ccc12
