Task: Answer the multiple choice question.
Query: Which compound exhibits a 1.330% human ether-à-go-go related gene (hERG) inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
[a] COC(=O)CN1C(=O)C(O)=C(C(C)=O)C1c1ccc([N+](=O)[O-])cc1
[b] CCc1ccc(C(=O)C23CN4CN(CN(C4)C2)C3)cc1
[c] CCOc1ccc(C)cc1S(=O)(=O)NC1CCCCCC1
[d] CCCCn1c(N)c(N(CC)C(=O)Cc2ccc(S(=O)(=O)N3CCOCC3)s2)c(=O)[nH]c1=O
Answer: a. COC(=O)CN1C(=O)C(O)=C(C(C)=O)C1c1ccc([N+](=O)[O-])cc1
