Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a 1.337\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a CCCCOC(=O)c1[nH]c(C)c(C(=O)OC)c1C
b O=C(/C=C/c1ccc(Cl)cc1)Nc1ccc(CN2CCOCC2)cc1
c CCOC(=O)C1CCCN(C(=O)c2ccc(Cn3c(=S)[nH]c4cc(C(=O)OC)ccc4c3=O)cc2)C1
Answer: b. O=C(/C=C/c1ccc(Cl)cc1)Nc1ccc(CN2CCOCC2)cc1
