Task: Answer the multiple choice question.
Question: Which drug has a 1.899\% 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) CCCN1CCO[C@@H]2c3cc(O)ccc3OC[C@H]21.Cl
(b) COC(=O)c1ccc(S(=O)(=O)N2CCC(O)CC2)n1C
(c) C=CCc1cccc(C2Nc3ccccc3C(=O)N2O)c1O
(d) NCCCNC(=O)c1cc2ccccc2[nH]1
Answer: c. C=CCc1cccc(C2Nc3ccccc3C(=O)N2O)c1O
