Task: Answer the multiple choice question.
Question: Which compound exhibits a 4.842\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
[a] COc1ccc(N(CC(=O)Nc2ccc(Cl)cc2)S(=O)(=O)c2c(C)n[nH]c2C)cc1
[b] COCCc1ccc(OCC(O)CNC(C)C)cc1.O=C(O)[C@H](O)[C@@H](O)C(=O)O
[c] CC(=O)NC(c1cccs1)c1cc([N+](=O)[O-])c2cccnc2c1O
[d] CCOP(=S)(OCC)N1CCOCCOCCN(P(=S)(OCC)OCC)CCOCCOCC1
Answer: b. COCCc1ccc(OCC(O)CNC(C)C)cc1.O=C(O)[C@H](O)[C@@H](O)C(=O)O
