Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a 0.380\% 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 CC1=C(C(=O)OCC2CCCO2)C(c2coc3ccccc3c2=O)C2=C(CCCC2=O)N1
b CCCNC(=O)c1nc(C)c(C)nc1C(=O)Nc1cccc(Cl)c1
c Cc1ccc(NC(=O)CCc2nc3sc4c(c3c(=O)[nH]2)CCCC4)c(Br)c1
d C[C@@H]1C=C[C@](Cc2ccccc2)(C(=O)O)N1C(=O)c1ccccc1
Answer: a. CC1=C(C(=O)OCC2CCCO2)C(c2coc3ccccc3c2=O)C2=C(CCCC2=O)N1
