Task: Answer the multiple choice question.
Question: Which drug exhibits a 9.165\% 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] COc1cccc(COC(=O)Cc2ccc(S(=O)(=O)N3CCOCC3)s2)c1OC
[b] COc1cc(C(=O)OCC(=O)Nc2cccc(S(=O)(=O)N3CCCC3)c2)ccc1OCC(C)C
[c] O=C(c1cc(-c2cccc(Cl)c2)on1)N1CCN(c2ccccc2)CC1
[d] Cl.O.O=C1C2CCCCN2C(=O)N1CCCCN1CCN(c2ccccc2Oc2ccccc2)CC1
Answer: c. O=C(c1cc(-c2cccc(Cl)c2)on1)N1CCN(c2ccccc2)CC1
