Task: Answer the multiple-choice question.
Question: Which drug exhibits a -1.905\% 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) OCC[C@H]1C[C@H](O)[C@@H](O)[C@@]2(CCCO2)O1
b) C#CCOCCOCCOCCNc1nc(N2CCN(C(=O)C([C@@H](C)CC)n3cc(C(N)CO)nn3)CC2)nc(N2CCN(C(=O)C([C@@H](C)CC)n3cc(C(N)COC(=O)C(F)(F)F)nn3)CC2)n1.Cl
c) COc1ccc(CCNC(=O)Cc2ccsc2)cc1
d) C=CCNC(=O)/C(=C\C=C\c1ccccc1)NC(=O)c1ccccc1Cl
Answer: d. C=CCNC(=O)/C(=C\C=C\c1ccccc1)NC(=O)c1ccccc1Cl
